The velocity of a body is its speed in a given direction. If the body changes direction it changes velocity, even if its speed stays the same.
If the velocity of a body changes, we say that is accelerates.
we can calculate acceleration using the equation:
acceleration=change in velocity/time taken for the change
The SI unit of acceleration is meters per second squared. (when answering questions in the exam always put…
