Acceleration is any change in velocity during a length of time.
Momentum = (mass) x (velocity vector).Given constant velocity, and assuming that mass doesn't change,there is no change in momentum over time.If there is any change in momentum, it can only be due to a change in mass.It would change in direct proportion to the mass, and the direction of themomentum vector would remain constant, in the direction of the velocity.

velocity dx/dt
Acceleration is a change in velocity over time - (change in velocity) / (time difference). So, you basically need two velocity measurements (or two assumed velocities), and the time difference between the measurements.
This is normally referred to as "instantaneous velocity" although if there is no change in velocity with respect to time - that is, no acceleration or deceleration - you might simply refer to it as "velocity".
Change in velocity = Velocity at the end of the period minus velocity at the start of the period.
Velocity is speed in a given direction Acceleration is the rate in which you change velocity.
Kinetic energy is equal to potential energy during the change
You can't. Acceleration is change in velocity. If given a constant velocity, the acceleration is zero.

Force equals the mass times the rate of change of the velocity.
Momentum = (mass) x (velocity vector).Given constant velocity, and assuming that mass doesn't change,there is no change in momentum over time.If there is any change in momentum, it can only be due to a change in mass.It would change in direct proportion to the mass, and the direction of themomentum vector would remain constant, in the direction of the velocity.

You cannot. Force = Mass*Acceleration or Mass*Rate of change of Velocity.
