What does the direction of force depend on?
The direction of the force depends on the acceleration. The direction of the momentum rests on the direction of the velocity. The force is inversely proportional to time, that is; with the increase in time, the force decreases. The momentum is directly proportional to time;, that is; with the increase in time, the momentum also increases.
Is force inversely proportional to time?
In general, no, force is in no way inversely proportional to time although you could build some system where it is so. 1 Share ReportSave More posts from the Physics community 2.0k
What is the relationship between momentum and force?
The direction of the momentum rests on the direction of the velocity. The force is inversely proportional to time, that is; with the increase in time, the force decreases. The momentum is directly proportional to time; that is; with the increase in time, the momentum also increases.
Is force directly proportional to acceleration?
If the acceleration of an object is directly proportional to the net force which it experiences, then any increase in net force will increase the acceleration. Similarly, any decrease in net force will decrease the acceleration. What is force directly proportional to?
Is time proportional to force?
The force is inversely proportional to time, that is; with the increase in time, the force decreases. The momentum is directly proportional to time;, that is; with the increase in time, the momentum also increases. For constant acceleration, this quantity does not change.
What is force directly proportional to?
According to Newton's second law of motion, force is directly proportional to the rate of change of momentum provided.
Is force indirectly proportional to time?
Well, in Newtonian mechanics force is equal to the change in momentum (or impulse) divided by the duration of impulse, or time. So yes, by the equation F=dp/dt (or delta p and delta t if one isn't acquainted with calculus), force is inversely proportional to the change in time.
What is directly proportional to time?
The distance traveled by a body, moving with uniform acceleration, is directly proportional to time.
What is force inversely proportional to?
Thus, force is inversely proportional to distance squared.
Is force directly proportional to mass?
net force is directly proportional to mass when acceleration is constant.
Is force and time inversely related?
From Equation 1, force is inversely proportional to time.
Does force increase with time?
Observe that the greater the time over which the collision occurs, the smaller the force acting upon the object. Thus, to minimize the effect of the force on an object involved in a collision, the time must be increased.
Is gravity directly proportional to time?
2.2. The rate of flow of time is fastest in empty space, and slows down in the presence of matter-energy 1. So, gravity is proportional to time and gravity is inversely proportional to velocity.
What is inversely proportional to time?
Speed and travel time are inversely proportional because the faster we travel, the lesser is the time taken, i.e. greater the speed, the lesser the time. As speed increases, travel time decreases.
Is time directly proportional to mass?
Mass is directly proportional to time, if time slows down then mass goes down or decreases. From a Relativistic perspective: Approaching c, time slows down and mass goes up or increases. Mass is inversely proportional to time.
Is time directly proportional to velocity?
The displacement of a moving object is directly proportional to both velocity and time. Acceleration compounds this simple situation. Now the velocity is also directly proportional to time.
Is force is directly proportional to acceleration?
So acceleration of an object is directly proportional to the net force acting upon the object, and inversely proportional to the mass of the object.
Is force directly proportional to gravity?
So for Newton, the force of gravity acting between the earth and any other object is directly proportional to the mass of the earth, directly proportional to the mass of the object, and inversely proportional to the square of the distance that separates the centers of the earth and the object.
Is force directly proportional to friction?
Force of friction is directly proportional to the weight of the body. It does not depend on the size of the body and the area of the surfaces in contact.
Is force directly proportional to torque?
Torque is the rotational equivalence of linear force. Power is the rate of doing work. The relation between torque and power is directly proportional to each other. The power of a rotating object can be mathematically written as the scalar product of torque and angular velocity.
How does the direction of the force depend on the acceleration?
The direction of the force depends on the acceleration. The direction of the momentum rests on the direction of the velocity. The force is inversely proportional to time, that is; with the increase in time, the force decreases.
What is the difference between momentum and force?
However, force refers to the amount that changes the amount of action present when acted upon any object. The amount of motion encompassed within a moving object refers to a momentum.
What does it mean when momentum and velocity change?
It means that with the increasing time, there will be a decrease in the amount of force if the momentum remains constant. Momentum and force both have magnitude as well as direction. It means both are vector quantities. If the velocity changes, then from the formula; p = mv; momentum also changes.
What is the force that causes momentum change?
A force refers to the external action of pushing or pulling something, which results in the momentum change. It is a vector quantity whose direction depends on the acceleration direction. An unbalanced force applied to the body results in the movement of that object. However, the force acted in a balanced way results in equal magnitude but opposite direction. As a result, the net effect cancels out.
How does momentum change?
If you know the amount of force to apply, you change its momentum with the applied force. Force defines the rate with which momentum of an object changes. Momentum is all about the motion of an object. If an object moves with a double velocity, his momentum doubles, Force cause the change in momentum of the object as you change its speed. So, momentum is the multiple of force and time. But if you keep applying force for a particular time, it will change its momentum. It follows the third law of motion by Newton.
How to find force and momentum?
Force and momentum relation is given by the equation: F=dp/dt. The second law of motion gives the following equation as stated by Newton. The law states that the change in momentum of any object is given by mass into acceleration, that is, force.
What is mass times velocity?
Mass times velocity of any object stands as momentum.
Why are speed and travel time inversely proportional?
Speed and travel time are Inversely Proportional because the faster we go the shorter the time. As speed goes up, travel time goes down. And as speed goes down, travel time goes up.
What is the constant of proportionality?
The "constant of proportionality" is the value that relates the two amounts
Why does the brightness decrease as the square of the distance?
In fact the brightness decreases as the square of the distance. Because the light is spreading out in all directions.
What happens to painting time as the number of people goes up?
As the number of people goes up, the painting time goes down.
What is direct proportional?
Directly proportional: as one amount increases, another amount increases at the same rate.
Is the distance it falls proportional to the square of the time of fall?
The distance it falls is proportional to the square of the time of fall.
