Explanation:
Motion is when a body changes position in space with respect to time. There are four types of motion namely
1. circular motion: this is the motion of an object along a circular path eg. the motion of a car tyre.
2. random motion: it is the motion of a body in zigzag manner e.g the motion of smoke from the exhaust pipe of a vehicle as it rises into the atmosphere
3. oscillatory : also known as the to and fro movement of a body e.g a pendulum swing
4. Linear motion: The motion of a body on a straight line. also known as translational motion e.g the motion of a car
Parameters/ terminologies used in motion are
velocity
displacement
distance
acceleration,
time,
speed
Motion in space and time starts from a point known as Origin
