Question

What are uniform and non-uniform motion?

Answer 1

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 and exactly converse of it is the definition of non-uniform motion use this concept to differentiate between uniform and non-uniform motion.

Complete Step-by-Step solution:
Uniform motion:
A body is said to be in uniform motion if it covers equal distances in equal intervals of time.
For example:
$\left( 1 \right)$ A car travels with the speed of 20 m/s. It means that the car covers 20 meter in 1 second, so the speed is constant in every second.
$\left( 2 \right)$ Movement of blades of a ceiling fan.
Non-uniform motion:
A body is said to be in non-uniform motion if it covers unequal distances in equal intervals of time.
For example:
$\left( 1 \right)$ If a car covers 10 meters in first second and 15 meters in next second so this is non-uniform motion.
$\left( 2 \right)$ The motion of a train (as the train always covers unequal distances in every interval of time).
So this is the required answer.

Note – There are some important points relating to uniform and non-uniform motion that help solving problems of this type. In uniform motion the actual speed and the average speed of the moving body is also the same, however it is not true in case of a non-uniform motion.
