Question

Explain different types of motion.

Answer 1

In physics, motion, can be classified as below.

1. Linear motion: Motion along a straight line.
2. Circular motion: Motion along a circular path.
3. Oscillatory motion: Repetitive to and fro motion of an object at regular interval of time.
4. Random motion: Motion of the object which does not fall in any of the above categories.
5. Uniform and Non-uniform motion:
   1. Uniform motion: Consider a car which covers 60 km in the first hour, 60 km in second horn-, and another 60 km in the third hour and so on. The car covers equal distance at equal interval of time. We can say that the motion of the car is uniform. An object is said to be in uniform motion if it covers equal distances in equal intervals of time howsoever big or small these time intervals may be.
   2. Non-uniform motion: Now, consider a bus starting from one stop. It proceeds slowly when it passes through a crowded area of the road. Suppose, it manages to travel merely 100 m in 5 minutes due to heavy traffic and is able to travel about 2 km in 5 minutes when the road is clear. Hence, the motion of the bus is non-uniform i.e. it travels unequal distances in equal intervals of time.
