What is the difference between a projectile and a trajectory?
What is the difference between projectile motion and trajectory? The path that the object follows is called its trajectory. Projectile motion only occurs when there is one force applied at the beginning, after which the only influence on the trajectory is that of gravity.
What exactly is a projectile?
So what exactly is a projectile? A projectile is any object propelled with massive amounts of force acting upon it. For example, a fire arm is considered a projectile, because the bullet has a small explosive charge, then that cause a chain of reaction.
What is the formula for projectile?
Projectile Motion Formulas. A projectile is an object that is given an initial velocity, and is acted on by gravity. Velocity is a vector (it has magnitude and direction), so the overall velocity of an object can be found with vector addition of the x and y components: v 2 = v x 2 + v y 2.

Noun Projectiles shot from a gun at high speed bullets shells slugs pellets lead shots ammo ammunition bolts buckshots caps balls cartridges gunshots rounds cannonballs missiles rockets small missiles darts arrows bombs buckshot shafts barbs mortar explosives grenades torpedoes reed quarrels charge canisters
What do you mean by projectile class 11?
A projectile is any object thrown into space upon which the only acting force is gravity.
What is a projectile defined as?
A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity. By definition, a projectile has a single force that acts upon it - the force of gravity.
What is a projectile and examples?
A projectile is any object that is cast, fired, flung, heaved, hurled,pitched, tossed, or thrown. you throw the ball straight upward, or you kick a ball and give it a speed at an angle to the horizontal or you just drop things and make them free fall; all these are examples of projectile motion.
What is projectile called in one sentence?
When projectile refers to a weapon, it is always propelled by something else. Think of the bullet in a gun or a spear thrown by a person. A rocket, which is self-propelled, is also called a projectile. As an adjective, projectile means "propelled forward" as in a projectile force or weapon.
Is a Plane a projectile?
Airplanes, guided missiles, and rocket-propelled spacecraft are sometimes also said to follow a trajectory. Since these devices are acted upon by the lift of wings and the thrust of engines in addition to the force of gravity, they are not really projectiles.
What are the types of projectile?
Three types of projectiles— the bullet, the round ball, and shot—are used in muzzleloaders. Most are cast from pure lead. The ethical hunter experiments with several projectile types and weights to see what will work best in a particular firearm for the game being hunted.

What Is a Projectile?
A projectile is any object that is thrown or launched into the air and then is only influenced by the force of gravity. For an object to become a projectile, some initial force must be imparted upon it. A baseball that has been hit by a batter, a cannonball fired from a cannon or a diver jumping from a diving board are all examples of projectiles. In each case, some force is applied, by the bat, the cannon, or the diving board, after which the object will undergo projectile motion.
What are some examples of projectiles?
An example of a projectile is a baseball hot by a batter. The trajectory of the baseball depends only on the initial velocity and angle of the hit, and acceleration due to gravity.
What is the trajectory of a projectile?
After an object is launched, it moves along a path known as the trajectory. Projectile motion describes the trajectory of the projectile and is only dependent on the initial speed, the launch angle, and the acceleration due to gravity. The initial speed, or velocity, is the speed at which the object is moving when it is first propelled into the air. The launch angle describes the angle, from horizontal, that the object is launched. The speed and angle of a baseball the instant that it leaves the bat will determine the maximum height, the range, and flight time. It is important to note that after an object is launched into the air, it is only acted upon by the force of gravity assuming negligible air resistance.
What are the key parameters of projectile motion?
As a result of the predictable trajectory, kinematic equations have been defined which relate the key parameters for projectile motion. These equations of motion relate the initial and final velocities, the displacement, time of flight, and acceleration of the projectile. Assuming the right amount of information is known, they can be used to calculate these variables. The final velocity can be calculated if the initial velocity, acceleration, and time of flight are known, using
How to determine the horizontal component of the initial velocity?
The horizontal component of the initial velocity can be determined using the initial velocity and launch angle
How does velocity affect the height of a projectile?
Increasing or decreasing the initial velocity or launch angle will change the maximum height and range of the projectile. A higher initial velocity will result in a greater height and range. Increasing the launch angle affects the maximum height and range differently. The angle that results in the greatest maximum height will likely not result in the greatest range.
Is the horizontal displacement of a projectile dependent on the initial velocity?
And the horizontal displacement, or range, of the projectile, is dependent on the horizontal component of the initial velocity and flight time, according to
What is Projectile Motion?
When a particle is thrown obliquely near the earth’s surface, it moves along a curved path under constant acceleration that is directed towards the centre of the earth (we assume that the particle remains close to the surface of the earth). The path of such a particle is called a projectile and the motion is called projectile motion.
What is the primary force acting on a projectile?
A projectile is any object thrown into space upon which the only acting force is gravity. The primary force acting on a projectile is gravity. This doesn’t necessarily mean that other forces do not act on it, just that their effect is minimal compared to gravity.
What is the motion of a particle thrown obliquely near the Earth's surface called?
The path of such a particle is called a projectile and the motion is called projectile motion.
What is the point of projection?
The point O is called the point of projection; θ is the angle of projection and OB = Horizontal Range or Simply Range. The total time taken by the particle from reaching O to B is called the time of flight.
When does the height of a projectile reach its maximum value?
The height of the projectile is given by the component y, and it reaches its maximum value when the component V y V y is equal to zero. That is when the projectile changes from moving upward to moving downward.
Is a body thrown near the surface a two dimensional motion?
This implies that as long as a body is thrown near the surface, the motion of the body can be considered as a two-dimensional motion, with acceleration only in one direction.
What is a projectile?
Defining Projectiles. A projectile is an object upon which the only force acting is gravity. There are a variety of examples of projectiles. An object dropped from rest is a projectile (provided that the influence of air resistance is negligible). An object that is thrown vertically upward is also a projectile ...
Why is a projectile horizontal?
The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity. Due to the absence of horizontal forces, a projectile remains in motion with a constant horizontal velocity. Horizontal forces are not required to keep a projectile moving horizontally.
What is the only force acting on an upward moving projectile?
Many students have difficulty with the concept that the only force acting upon an upward moving projectile is gravity. Their conception of motion prompts them to think that if an object is moving upward, then there must be an upward force. And if an object is moving upward and rightward, there must be both an upward and rightward force.
What is the force of gravity in a projectile?
By definition, a projectile has a single force that acts upon it - the force of gravity. If there were any other force acting upon an object, then that object would not be a projectile. Thus, the free-body diagram of a projectile would show a single force acting downwards and labeled force of gravity (or simply F grav ).
What force is there when an object is moving upward?
And if an object is moving upward and rightward, there must be both an upward and rightward force. Their belief is that forces cause motion; and if there is an upward motion then there must be an upward force. They reason, "How in the world can an object be moving upward if the only force acting upon it is gravity?".
Is an object thrown vertically upward a projectile?
An object that is thrown vertically upward is also a projectile (provided that the influence of air resistance is negligible). And an object which is thrown upward at an angle to the horizontal is also a projectile (provided that the influence of air resistance is negligible).
Is a projectile a free body?
By definition, a projectile is any object upon which the only force is gravity.
What is projectile motion?
Projectile Motion. Projectile refers to an object that is in flight after being thrown or projected. In a projectile motion, the only acceleration acting is in the vertical direction which is acceleration due to gravity (g). Equations of motion, therefore, can be applied separately in X-axis and Y-axis to find the unknown parameters.
What are the two parts of projectile motion?
The projectile motion consists of two parts – one is the horizontal motion of no acceleration and the other vertical motion of constant acceleration due to gravity. The projectile motion is always in the form of a parabola which is represented as:
What is the horizontal component of initial velocity?
If any object is thrown with the velocity u, making an angle Θ from horizontal, then the horizontal component of initial velocity = u cos Θ and the vertical component of initial velocity = u sin Θ. The horizontal component of velocity (u cos Θ) remains the same during the whole journey as herein, no acceleration is acting horizontally.
What is the angle between velocity and acceleration?
The velocity of the body at the highest point is u cos Θ in the horizontal direction. However, the angle between the velocity and acceleration is 90 degree.
What is motion in a plane?
Motion in a plane is also referred to as a motion in two dimensions. For example – Circular Motion, Projectile Motion, etc. For the analysis of such type of motion (i.e. Projectile Motion), the reference point will be made of an origin and the two coordinate axes X and Y. One of the most common examples of motion in a plane is Projectile motion.
When a particle is projected obliquely near the Earth’s surface, it moves simultaneously in the direction?
When a particle is projected obliquely near the earth’s surface, it moves simultaneously in the direction of horizontal and vertical. The motion of such a particle is called Projectile Motion. In the above diagram, where a particle is projected at an angle θ, with an initial velocity u. For this particular case, we will calculate the following:
Is the acceleration of a projectile constant?
Throughout the motion, the acceleration of projectile is constant and acts vertically downwards being equal to g.

What does projectile vomiting feel like?
It’s typically accompanied by a wave of nausea, and a queasy feeling in the stomach afterward. . Projectile vomiting is when your body expels vomit with more force than usual. It’s one of your body’s reactions to something it recognizes as toxic, but there are medical conditions that can cause projectile vomiting as well.
Can a virus cause projectile vomiting?
Some viral infections can cause projectile vomiting. Norovirus is one example. It’s easily spread from person to person through contact with droplets and feces. Since projectile vomit can reach up to four feet, the droplets can also spread that far to contaminate others. Intracranial pressure.
Can projectile vomiting cause sickness?
Most cases of projectile vomiting are short-lived, but extended sickness and vomiting can cause complications. Dehydration is the most common problem associated with all vomiting, but especially with this forceful type. It can happen when your stomach is expelling its contents and you’re unable to hold anything down.
