Explanation:
The force is distributed in two categories i.e
Contact Forces are the forces which is requires a contact between two bodies to occur.
The Types of contact forces are given below:
- Tension Force
- Normal Force
- Air Resistance Force
- Applied Force
- Spring Force
Some common daily examples of the contact force are
- Frictional force between the tyres of a moving vehicle and the road.
- Air flowing in opposite direction of a moving object.
- Pushing a table with hand and the friction between its base and floor.
- Stretching a rubber band with hands etc.
Also non-contact forces are Gravitational force, Electrical force and Magnetic force.
