What is the physical meaning of momentum?
Momentum is the tendency of a body to stay in motion. A body in motion stays in motion unless a force stops it or alters its motion. As other answer have written, momentum is defined as mass time velocity, so the more mass and/or the higher the velocity the harder it is to stop or alter the body that is motion.
How to calculate momentum.?
Momentum can be calculated using this equation: p = m × v where: p is the momentum in kilograms metres per second, kg m/s
What is the meaning of 'moment' in physics?
cross-product indicates an axis and gives a notion of rotational direction: clockwise vs counterclockwise. Moment is basically a measurement of how the mass is distributed about a point or axis. The larger the values, the more torque is needed to spin it. You would want to calculate about an axis if you're designing a rotating part.
Which statement correctly describes Momentum?
total momentum. Choose the statement below which correctly defines or describes momentum. Momentum is the quantity of motion, mass times velocity. a force drawing the body toward the center and increasing with distance away from the center. A figure skater is spinning with her arms extended.
What is the simple definition of momentum?
: a property of a moving body that the body has by virtue of its mass and motion and that is equal to the product of the body's mass and velocity broadly : a property of a moving body that determines the length of time required to bring it to rest when under the action of a constant force.
What is momentum in physics with example?
-A truck full of goods has a large mass and so it must slow down before a stop light because it has the large momentum with the same velocity and so it is very difficult to stop. -A moving bullet has a large momentum since it has an extremely large velocity though it carries very small mass.
Who defined momentum?
At this point, we introduce some further concepts that will prove useful in describing motion. The first of these, momentum, was actually introduced by the French scientist and philosopher Descartes before Newton.
What is the definition of momentum in physics GCSE?
A moving object has momentum. This is the tendency of the object to keep moving in the same direction. It is difficult to change the direction of movement of an object with a lot of momentum. Momentum can be calculated using this equation: p = m × v.
What is the unit of momentum?
Therefore, the unit for momentum can be Newton-second (Ns). In the CGS system, if the mass is in grams and the velocity in centimeters per second, then the unit of momentum will be gram-centimeters per second (g⋅cm/s).
What is another word for momentum?
In this page you can discover 14 synonyms, antonyms, idiomatic expressions, and related words for momentum, like: motion, force, energy, velocity, angular momentum impulse, impetus, thrust, tide, market share, dynamism and drive.
Is momentum is a force?
Momentum is all about the motion of an object. If an object moves with a double velocity, its momentum doubles. The force causes the change in momentum of the object as you change its speed. So, momentum is the multiple of force and time.
What is momentum and velocity?
Momentum is defined as the quantity of motion of the body. It is measured by “mass × velocity”, as momentum depends upon velocity, and it depends on the direction of the motion of the body as well. Momentum is a vector quantity since velocity is a vector while mass is scalar. Momentum = Mass X Velocity. p = mv.
How do you find momentum?

What is a real life example of momentum?
A tennis ball that hits on the racket with a high velocity has a smaller momentum (because of its less mass). So even if the player hits a tennis ball with less force, it will go to a greater distance.
How do you find momentum examples?
Example: What is the momentum of a 1500 kg car going at highway speed of 28 m/s (about 100 km/h or 60 mph)?p = m v.p = 1500 kg × 28 m/s.p = 42,000 kg m/s.
What are 3 examples of impulse?

How do you explain momentum to students?
One very simple way to demonstrate momentum is to roll a small ball or toy car down a ramp so it collides with another ball or toy car at the bottom. As the ball or car rolls down the ramp its momentum increases as it picks up speed. The object at the bottom is stationary until the first object collides with it.
How to describe momentum?
Momentum is a vector quantity. As discussed in an earlier unit, a vector quantity is a quantity that is fully described by both magnitude and direction. To fully describe the momentum of a 5-kg bowling ball moving westward at 2 m/s, you must include information about both the magnitude and the direction of the bowling ball. It is not enough to say that the ball has 10 kg•m/s of momentum; the momentum of the ball is not fully described until information about its direction is given. The direction of the momentum vector is the same as the direction of the velocity of the ball. In a previous unit, it was said that the direction of the velocity vector is the same as the direction that an object is moving. If the bowling ball is moving westward, then its momentum can be fully described by saying that it is 10 kg•m/s, westward. As a vector quantity, the momentum of an object is fully described by both magnitude and direction.
What is momentum in sports?
Momentum is a commonly used term in sports. A team that has the momentum is on the move and is going to take some effort to stop. A team that has a lot of momentum is really on the move and is going to be hard to stop. Momentum is a physics term; it refers to the quantity of motion that an object has.
How does momentum work?
Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
What is the momentum of a 2.0 kg cart?
Similarly, if the 2.0-kg cart had a velocity of 8.0 m/s (instead of 2.0 m/s), then the cart would have a momentum of 16.0 kg•m/s (instead of 4.0 kg•m/s). A quadrupling in velocity results in a quadrupling of the momentum. These two examples illustrate how the equation p = m•v serves as a "guide to thinking" and not merely a " plug-and-chug recipe for algebraic problem-solving."
What is the direction of the momentum vector?
The direction of the momentum vector is the same as the direction of the velocity of the ball. In a previous unit, it was said that the direction of the velocity vector is the same as the direction that an object is moving.
What is the symbol for momentum?
In physics, the symbol for the quantity momentum is the lower case p. Thus, the above equation can be rewritten as
What is the standard metric unit of momentum?
The standard metric unit of momentum is the kg•m/s. While the kg•m/s is the standard metric unit of momentum, there are a variety of other units that are acceptable (though not conventional) units of momentum. Examples include kg•mi/hr, kg•km/hr, and g•cm/s.
How to find momentum in physics?
In physics, we define momentum mathematically as the multiplication of mass and velocity as seen in this equation: p = m * v
What does it mean to gain momentum?
Gaining Momentum. Momentum is a word you're probably very familiar with. Often, you'll hear that something is gaining or gathering momentum . It might be an actual moving object or it might be used more metaphorically like with a sports team.
How to express conservation of momentum?
We know the momentum is conserved, so the total momentum before the collision must equal the total momentum after the collision. We'll call the momentum before the collision the initial momentum ( i ), and the momentum after the collision the final momentum ( f ). Total initial momentum equals total final momentum:
How is momentum transferred?
How momentum is transferred depends on the type of collision. There are three types of collisions: elastic, perfectly inelastic, and partially inelastic.
What is the principle of conservation of momentum?
The principle of conservation of momentum states that in an isolated system, two objects that collide have the same combined momentum before and after the collision. That is, momentum is not destroyed in the collision, but transferred between the two objects.
What does momentum mean in baseball?
We know that momentum is the quantity of motion of a moving body, but what, exactly, does that mean? Let's think about a baseball being thrown in a straight line through the air in order to try and understand this. When you catch a baseball, you feel the momentum of the ball being imparted to you. The ball will probably push your hand back towards you when you catch it. The more momentum the ball has, the more it will push back your hand as it transfers its momentum to you.
Why do we keep the mass of two objects defined separately as m 1 and m 2?
This is because the mass of the two objects remains the same before and after the collision. Even though we used two pool balls in our example, you can't always guarantee that the two objects' masses will be the same , so we do keep the masses defined separately as m 1 and m 2 in the equation.
What is momentum in particle?
Conversely, the momentum of a particle is a measure of the time required for a constant force to bring it to rest. The momentum of any collection of particles is equal to the vector sum of the individual momenta.

Linear Momentum
The Conservation of Momentum Principle
- The principle of conservation of momentumstates that in an isolated system, two objects that collide have the same combined momentum before and after the collision. That is, momentum is not destroyed in the collision, but transferred between the two objects. In an isolated system, momentum is always conserved in a collision. In the example of you catching a baseball, the mo…
Elastic Collision
- In an elastic collision, two objects collide and bounce off of each other. A good example of this type of collision would be a game of pool. You hit the cue ball with the cue, and it bounces off another ball. Hopefully, that other ball goes in the table pocket, but what's most important for us is that the two balls don't stick together at all. They bounce off of each other. We can also express …
Bowling Problem
- Now let's try an example with this equation and unlike the pool balls, we'll use two objects with different masses. Imagine you've gone bowling and a child before you rolled the ball so slowly it stopped mid-lane. No one is around to help you and you don't want to walk out on the lane yourself. You decide to roll your bowling ball into the one stopped on the lane to get it moving. Y…
