Answer:
two types of motion
▪uniform motion
when is body covers equal distance in equal interval of time.

when a body covers unequal distances in equal interval of time

Types Of Motion:
We might have noticed that different objects move differently. Some objects move in a curved path, some in a straight path and 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 in 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.
