Question
Define uniform velocity and give one example.
Solution
When a body covers equal distances in equal intervals of time (however small may be the time interval) in a specified direction, the body is laid to be moving with uniform velocity.
Example: A car moving on a straight road with constant speed has uniform velocity.
