what is force in Physics explain it ?
Answers
▶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.
✨Force is a push or pull which results in interaction between two bodies
⭐Force is of 2 types :-
⏩If net force is 0 it is balanced force
⏩Non zero force is unbalanced force
#EFFECTS OF FORCE:-
⏩A force can move a body from rest.
⏩ can stop a body from motion.
⏩change the direction of moving body.
⏩ can change the shape and size of a body.
▶The forces are mainly divided on the basis of when it acts.
#The types of forces are given below : -
1. Contact Forces
Examples: Frictional Force, Muscular Force, Force of Tension, etc.
2. Non-contact Forces
Examples: Gravitational Force, Electrostatic Force, Magnetic Force, etc.

- Force is push or pull acting on a body which tends to change its state of rest or of motion. It is denoted by "F". It has a magnitude and a direction.

Here,
- " m " = Mass of the body
- " a " = Acceleration
- " F " = Force

Unit of Force :-
- SI unit of force is Newton(N).
- C.G.S (centimetre gram second) unit of force is Dyne.
Effects of force -
- Force can change the direction of a moving object.
- Force can change the shape and size of an object.
- Force can change the speed of a moving object.
- Force can change a body′s state of motion or rest.
