What causes the change in velocity?
Any force causes acceleration i.e. change in 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.
If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Is there an acceleration when an object traveling at constant velocity and why?
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
Is Acceleration is the magnitude of average velocity?
No. Acceleration is (change of velocity) divided by (time interval in which it changed). If velocity doesn't change, then there is no acceleration.

How is the initial velocity zero but the acceleration is not?
Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]

What can forces cause a change in?
A force causes an acceleration. That implies that it will change: * The velocity, and * The momentum.
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.

No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
How do forces cause an object to change its speed?
A forces on an object m creates an acceleration a=f/m and acceleration causes a change in velocity a= dv/dt. This change in velocity can change the speed or direction or both.
What is the change in velocity over time?
acceleration a----->velocity=acceleration x time: v=a x t
Is Acceleration is the magnitude of average velocity?
No. Acceleration is (change of velocity) divided by (time interval in which it changed). If velocity doesn't change, then there is no acceleration.
