Motion repeated in equal intervals of time is called periodic motion. The earth rotates on its axis once in 24 hours. The duration of time is fixed as 24 hours. Therefore the rotation of the earth is a periodic motion.

Rotational motion:
A body moves along a circular path.
Without changing its position, about its own (fixed) axis.
Eg. Rotation of a spinning top.
Curvilinear motion:
A body moves along a curved path.
Changes its position with motion.
Eg. Throwing paper airplanes or paper darts.

Average speed = \(\frac{distence}{time}\)
= \(\frac{400}{5}\) = 80 km per hour
Average speed = \(\frac{distence}{time}\)
= \(\frac{400}{5}\) = 80 km per hour
Motion: The change of position of an object with respect to time is known as motion.
1. Based on Path:
Linear motion. – Ex.: Parade of the soldiers.
Curvilinear motion. – Ex.: Paper flight moving.
Circular motion. – Ex.: Swirling stone tied to the rope.
Rotatory motion. – Ex.: Rotating top.
Oscillatory motion. – Ex.: Clock pendulum.
Zigzag (irregular) motion. – Ex.: Motion of a bee.
2. Based on Duration :
Periodic motion. – Ex.: Motion of a bob of simple Pendulum.
Non-periodic motion. – Ex.: Swaying of the branches of a tree.
3. Based on Speed:
Uniform motion. – Ex.: Hour hand of a clock.
Non – uniform motion. – Ex.: Motion of a train, as it leaves a station.

When a motion is not in uniform interval, then such motion is called non-periodic motion.
When a motion is not in uniform interval, then such motion is called non-periodic motion.
Forces: Forces are push or pull by an animate or inanimate agency.
Types of Forces:
Contact forces;
Non – Contact forces.
1. Contact forces: The force that is executed by touching the body is a contact force Eg. Kicking the football
2. Non – Contact forces: The force is applied. Without touching the object then it is called noncontact force.
Forces can
(i) Change the states of the body from rest to motion or motion to rest.
(ii) Either change the speed or direction or both of the body.
(iii) Change the shape of the body.
