8th DAV

Answer 1

Hii There!!!!


⏭️Force is a push or a pull of an object which produces acceleration in a body resulting in the motion of an object on which it acts.


⏭️S.I unit of force is Newton "N".

⏭️Force causes,

◆ Change in the speed of a body.

◆ Change in the direction of motion of a moving body.

◆ It also changes shape of the body.


⏭️There are 2 types of forces :-

1) Balanced force.

Answer 2

Force is that cause which either changes or tends to change the shape, size, dimensions, state of rest, state of motion etc. of an object over which it acts.The SI unit of force is newton, denoted by N . The forces are mainly divided on the basis of when it acts. The types of forces are given below : -

1. Contact Forces

The forces that are applicable only when the objects under consideration are in actual physical contact with each other are called contact forces. Examples: Frictional Force, Muscular Force, Force of Tension, etc.

2. Non-contact Forces

The forces that are applicable even if the objects under consideration are not in actual physical contact are named non-contact forces. Examples: Gravitational Force, Electrostatic Force, Magnetic Force, etc.
