We might have noticed that different objects move differently. Some objects move in a curved path, some in a straight path and a few others in a different way. According to the nature of the movement, motion is classified into three types as follows:
- Linear Motion
- Rotary Motion
- Oscillatory Motion
Linear Motion
In linear motion, the particles move from one point to another in either a straight line or a curved path. The linear motion depending on the path of motion is further divided as follows
- Rectilinear Motion – The path of the motion is a straight line.
- Curvilinear Motion – The path of the motion is curved.
A few examples of linear motion are the motion of the train, football, the motion of a car on the road, etc.
Rotatory Motion
Rotatory motion is the motion that occurs when a body rotates on its own axis. A few examples of the rotatory motion are as follows:
- The motion of the earth about its own axis around the sun is an example of rotary motion.
- While driving a car, the motion of wheels and the steering wheel about its own axis is an example of rotatory motion.
Oscillatory Motion
Oscillatory motion is the motion of a body about its mean position. A few examples of oscillatory motion are
- When a child on a swing is pushed, the swing moves to and fro about its mean position.
- The pendulum of a clock exhibits oscillatory motion as it moves to and fro about its mean position.
- The string of the guitar when strummed moves to and fro by its mean position resulting in an oscillatory motion.
