Hint – A body is said to be in uniform motion if it travels equal distances in an equal interval of time, no matter how small these intervals may be, speed of the object is constant.
Complete step-by-step answer:
As we know that the motion of the object is said to be uniform motion if the speed of the object is constant.
Option (a) – Free falling body.
The motion of a freely falling body is an example of uniformly accelerated motion.as due to the gravitational pull of the earth the body covers an equal amount of velocity in equal intervals of time.
Option (b) – Motion of moon around earth.
Motion of the moon around earth is a rotational motion, the moon moves around the earth in a fixed circular axis so this type of motion in which a body moves around some fixed axis is called rotational motion.
Option (c) – A car moving with constant velocity.
A car moving with a constant velocity is an example of uniform speed because the speed of the car is constant.
So this is the required answer.
Hence option (C) is correct.
Note – Converse of the definition of uniform motion, a non-uniform motion is one in which the object covers dissimilar distances in an equal interval of time. In uniform motion the actual speed and the average speed of the moving body is also the same.
