Define Force. Also, name the different types of force.


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 x a 


Force is divided into two broad categories:

A.Contact Forces

1. Tension Force

2. Normal Force

3. Contact Force

4. Frictional Force

5. Air Resistance Force

6. Applied Force

7. Spring Force


B. Action at a distance Forces

1. Gravitational Force

2. Electrical Force

3. Magnetic Force
