Question

Define uniform motion. When does a body said to have variable velocity?​

Answer 1

Answer:

When a car is moving on a straight line without changing its speed, then we say it is moving with uniform velocity. Variable means that keeps on changing. So, when distance changes unequally with respect to change in time at equal intervals then velocity keeps on changing.

Answer 2

Answer:

when a body covers equal distance in straight line , equal intervals of time are called uniform motion

Explanation:

example when a car is moving on a straight line with out change its speed then we say it is moving uniform velocity

variable means that keeping on changing so when distance change unequally with respect to change in time at equal intervals then velocity keeps on changing
