Physics
Give one example of each of the following:
(a) Uniform velocity
(b) Variable velocity
(c) Variable acceleration
(d) Uniform retardation
Answer
(a) Uniform velocity — The rain drops reach on earth’s surface falling with uniform velocity.
(b) Variable velocity — The motion of a freely falling body is with variable velocity because although the direction of motion of the body does not change, but the speed continuously increases.
(c) Variable acceleration — The motion of a vehicle on a hilly (or crowded) road.
(d) Uniform retardation — Motion of a vehicle, reaching a destination.
