Question

Which of the following is an example of non-uniform motion?
A. Movement of an asteroid
B. A car coming to a halt
C. A bouncing ball
D. All of these

Answer 1

Hint: As we all know, when any body covers unequal distances in a particular interval of time, then the body is said to be in non-uniform motion, so here we will discuss which of the following option is an example of non-uniform motion by defining or explaining the non-uniform motion.

Complete answer:
Movement of an asteroid, a car coming to a halt and a bouncing ball, all cover unequal distances in a time interval, hence they all are examples of non-uniform motion.Non-uniform motion occurs when an object travels unequal lengths during a fixed period of time. For instance, suppose you're travelling from point A to point B. You first take a highway and go at a high speed. When you enter city traffic, though, you tend to travel slowly, and when you hit a highway, you tend to move quickly.

Or in simple words, Non-Uniform Motion is a type of motion in which an object moves at different speeds. This indicates that the object does not reach the same distance in the same amount of time. In the case of rectilinear motion, the acceleration of the body will be non-zero if the motion is not consistent.

Hence, the correct option is D.

Note:As we also know that, when any of the body is in non-uniform motion, then its velocity is also not uniform i.e. not constant. This means the velocity of the object moving with non-uniform velocity is either increasing or decreasing with time i.e. the object is accelerating or decelerating.
