1. Electrostatic Force: The force exerted by a charged body on another charged or uncharged body is known as Electrostatic Force.

2. Gravitational Force: the attractive force offered by a heavier body or celestial objects is called Gravitational force or the force of gravity.

3. Pressure: Pressure is defined as force acting per unit area.
$p \frac{f}{a}$
Where p is Pressure, f is force and a is area.
$1 \: pascal \: = \frac{1 \: newton}{1 {m}^{2} }$
