Motion with examples:
When a body changes its position with time, the body is said to be in motion.
Example: A moving car, an airplane flying in the air, the earth revolving around the sun, etc are examples of moving objects.
Types of Motion:
There are mainly three types of motion.
- Complex Motion
If a body moves along a straight line, its motion is called translation. The motion of a freely falling body or the motion of a car along a straight line are examples of translation motion.
When an object moves in a circular path about a fixed point or an axis, the motion is called rotation. The axis is called the axis of rotation.
If a body exhibits translational as well as a rotational motion simultaneously then it is said to be in a state of complex motion.
