Description: In this video, we will learn about the three equations of motion with constant acceleration with the help of some illustrations. Let us learn now.

Question

Define motion. What do you understand by the terms &lsquo;uniform motion&rsquo; and &lsquo;non-uniform motion&rsquo;? Explain with examples.

Accepted Answer

A body is said to be in motion when its position is changing continuously with respect to a fixed point and with respect to time.

Uniform Motion:
A body is said to have uniform motion, if it travels equal distances in equal intervals of time without changing direction, no matter how small these time intervals may be. For example, a car moving at a constant speed of $10$ meter per second will cover an equal distance of $10$ metres in every second and so it possesses uniform motion.

Non–uniform Motion:
A body is said to have non–uniform motion, if it travels unequal distances in equal intervals of time or it covers equal distances in equal intervals of time but changes its directions continuously during the motion, no matter how small these time intervals may be.

For example, the motion of a train starting from a railway station is non–uniform. When the train starts from station, it moves very slowly and covers a small distance in a small time interval (say, in $1$ second). In the next second, it covers more distance and so on. Thus, the train goes on increasing its speed.
