0Mainly, when the velocity doesn't change. Also, in the case of varying velocity, the instantaneous velocity might, for a brief instant, be equal to the average velocity.

Momentum is what mass times velocity is equal to.

when a car travels equal distance in equal intervals of time its velocity is uniform and equal

In that case, the velocity is said to be constant.

For the instantaneous value of average velocity, average speed and average velocity are equal.

When acceleration is zero.

the tangential velocity is equal to the angular velocity multiplied by the radius the tangential velocity is equal to the angular velocity multiplied by the radius

When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.

Because charge particles produces magnetic field which causes electromagnetic force that's why moving charges move with the velocity equal to the velocity of light.

The magnitude of the velocity is always equal to the speed. But velocity is a vector quantity (has a magnitude and direction) while speed is just a scalar quantity (only magnitude). So velocity and speed are never equal.

No, It is the average velocity.

No, momentum is not equal to the mass of an object divided by its velocity.

At a small time interval, the average velocity is approximately equal to the instantaneous velocity. However, the values of the average velocity and the instantaneous velocity approach each other , as the length of the time interval is decreased more and more.

Tangential velocity is equal to (mass x velocity^2)/radial distance

It's equal to the change in velocity (final velocity - initial velocity).

Velocity is a vector. The magnitude of the velocity - its absolute value - is its speed.

Yes. (if the initial velocity is zero) if not then velocity = initial velocity + acceleration x time

YES!!!!!!!!!!!! A body can have equal velocity and speed at the same time. for suppose a body is travelling at 20m/s in north direction then the speed of the body is also equal to 20m/s. hence speed and velocity are equal in this case.

The magnitude of average velocity of an object equal to its average speed if that object is moving with CONSTANT velocity.

you are still. motion is at rest.

speed and velocity becomes equal when a body is moving on a straight road without changing its direction.

That is the case when you are talking about instantaneous speed and velocity - or when the velocity is constant. In the case of an average speed and velocity, this relation does not hold.

No. Speed is the magnitude of the velocity vector. In order for two velocities to be equal, they must have equal magnitudes and equal (parallel) directions.

If the velocity is constant (i.e., there is no acceleration). Terminal velocity is an example, although any constant velocity would fit this description.

Angular velocity is equal to the change in theta / change in time theta equals the arc length/ radius
