What is a force? and how do we use it in our daliy life?

A force is a push or pull of an object that causes it to change velocity (to accelerate). Whenever there is an interaction between two objects, there is a force exerted on each of the objects.

The S.I unit of Force is Newton.

The formula for force implies that force is equal to mass multiplied by acceleration.

F = m $\times$ a

Force is divided into two broad categories:

Contact Forces

1.Tension Force

2.Normal Force

3.Contact Force

4.Frictional Force

5.Air Resistance Force

6.Applied Force

7.Spring Force

Action at a distance Forces

1.Gravitational Force

2.Electrical Force

3.Magnetic Force

Examples of force in daily activities are opening and closing the door, throwing the ball in air, etc.
