How is acceleration created?
Acceleration is created by a change in velocity, which can be due to a change in speed, direction, or both. This change in velocity results in a change in the object's momentum, leading to acceleration. An object can accelerate through the application of a force, such as gravity, friction, or propulsion.
Is friction the rate of change in velocity?
Acceleration is the rate of change in velocity. It has nothing to do with friction, unless friction is causing the change.
How is friction a force?
Due to friction velocity of a body gets reduced, reduction in velocity causes change in velocity. This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.
How is friction force?

This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.
Does a body moving with uniform acceleration have momentum?
Yes, a body moving with uniform acceleration has momentum. Momentum is the product of an object's mass and its velocity, and acceleration is the rate of change of velocity. As long as the object is moving and has mass, it will have momentum.
Is momentum is another term for acceleration?
No, momentum is not another term for acceleration. Momentum is a vector quantity that describes an object's motion, taking into account both its mass and velocity, while acceleration is the rate of change of velocity of an object.
Do acceleration and momentum mean the same thing?
No, acceleration and momentum are not the same. Acceleration refers to the rate of change of an object's velocity, while momentum is the product of an object's mass and velocity. Acceleration measures how quickly an object's velocity is changing, while momentum is a property that depends on both an object's mass and how fast it is moving.
Is acceleration used to calculate momentum?
You may see acceleration mentioned in a momentum problem; but if it's there, it's only purposeis to help you find the object's velocity.All you need to know in order to find momentum is the object's mass and velocity.
How do forces cause a change in an object's momentum?
A force acting on a body causes acceleration. Acceleration is measure of the rate of change in the object's velocity. As its velocity changes, its momentum, which is the product of its mass and velocity, will change.
How is force a force?
Due to friction velocity of a body gets reduced, reduction in velocity causes change in velocity. This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.
What can forces cause a change in?
A force causes an acceleration. That implies that it will change: * The velocity, and * The momentum.
Relationship between acceleration and momentum?
No. Momentum is defined as mass times velocity, acceleration is the rate of change of velocity. To be more accurate, velocity is a vector quantity, it has both magnitude and direction. Momentum is therefore also a vector quantity in the direction of the velocity with magnitude equal to the mass times the magnitude of the velocity: 1) p = mv Acceleration is also a vector quantity and in the direction of the change in velocity direction and represents the rate of change of velocity: 2) a = dv/dt Force is defined as the rate of change of momentum, and is therefore also a vector in the direction of the momentum change: 3) F = dp/dt Substituting 1) in 3) we get: 4) F = m(dv/dt) And since 2) defines dv/dt as acceleration we get: 5) F = ma In other words, force is mass times acceleration. Note: The assumption above is that mass remains constant. This is an approximation that remains true only for slow speeds in comparison with the speed of light. These equations do not hold when approaching the speed of light as mass increases, and in fact makes it impossible to actually accelerate something to the speed of light.
