Velocity can only be measured in relation to some specified point of rest, so there is no such thing as absolute velocity. All velocity is relative.

Zero velocity is also called?

Zero velocity is also called stationary or at rest.


What is the difference between relative velocity and absolute velocity?

One pretty important difference is that relative velocity exists and absolute velocity doesn't. Velocity is always measured and described relative to something. There's no such thing as the "real speed" of a moving object. In fact, according to a scientist who's riding on the object, it's not moving at all. (Close your eyes right now and feel the earth move ?)


Can the relative velocity of two bodies be greater than the absolute velocity of either?

Yes it can be!!! If two cars on a straight road head directly toward each other at a speed of 60mph (relative to the road), the velocity of one relative to the other is 120mph. This example arbitrarily uses the road as the reference for each car's speed, but there really is no such thing as "absolute velocity" and both cars would have a velocity of about 1000mph relative to the center of the Earth. According to Einstein's principles of "Relativity" all velocity is relative.


Another definition for acceleration?

Acceleration is the rate of change of velocity with respect to time. It describes how quickly an object's speed or direction is changing. Mathematically, acceleration is the derivative of velocity with respect to time.


Can your speed and velocity ever have the same magnitude?

Speed and velocity always have the same magnitude, becausespeed is the magnitude of velocity.The difference is that velocity has a direction but speed doesn't
