Expert Answer
Uniform Velocity :
(1) An object with uniform velocity covers equal distances in equal intervals of time
(2) An object with uniform velocity has a specified direction
Variable Velocity :
(1) An object with variable velocity covers unequal distances in equal intervals of time either in a specified direction
or in different direction in different time,
(2) if the direction of motion changes, even if it covers equal distances in equal intervals of time,
it is said to be moving with a variable velocity.
e.g., revolving fan at a constant speed has variable velocity.
