Question
Distinguish between uniform and non-uniform motion. Give one example of each.
Answer
Uniform motion
An object is said to be in uniform motion when it moves along a straight path, and covers equal distances in equal intervals of time, howsoever small these intervals of time may be.
Example: Motion of a body along a straight path covering equal distances in equal intervals of time.
Non-uniform motion
When an object, (1) moving along a straight path, covers unequal distances in equal intervals of time or (2) does not move along a straight path, its motion, is called a non-uniform motion.
Example: Motion of a free-falling object.
