Yes - that is the mathematical definition of momentum.

Both are vectors. But acceleration and velocity have different dimensions. Acceleration is defined as the rate of change of velocity.
That's because of the way acceleration is defined. It is defined as the rate of change of velocity (change of velocity / time, or in the more general case, dv/dt).
It's defined that way.
Momentum is defined as the product of the mass and the velocity. P = mv. As the body is at rest its velocity v = 0. Hence momentum P =0.
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.
Force is defined as mass times acceleration.Momentum is defined as mass times velocity. Acceleration is defined as the rate of change of velocity. Velocity is defined as the rate of change of location in space.
It is acceleration. The difference between final velocity and initial velocity, divided by the time is the AVERAGE acceleration. Remember, though that velocity is a vector. So if you are going round in a circle at a constant speed, your direction of motion is changing continuously and so you are always accelerating!
Both are vectors. But acceleration and velocity have different dimensions. Acceleration is defined as the rate of change of velocity.
No, since acceleration is defined as a change in velocity. If there is no change, there is no acceleration.
accelerationThe rate at which velocity changes is called "acceleration".

Changes.
acceleration
Acceleration is defined as the rate of change of velocity... so, yes.
Acceleration is the RATE OF CHANGE of velocity. That means that acceleration and velocity have different units.The only similarity is that both are defined as rates of change.
Since acceleration is defined as change of velocity divide by time, it has units of (velocity / time). acceleration x time = (velocity / time) x time = velocity
