Definition of Force

Force is any action that moves an object or alters its uniform motion in a given direction. Force is the product of mass of the objects and its acceleration. The greater the mass of the object, the greater the force required to move it. Examples of force are pull, push, tension forces and frictional force between surfaces. Force is measured in Newton.

Mathematical Expression of Force

F ά mass × acceleration F = ma, where m = mass and a = acceleration due to gravity

Types of Forces

There are two types of force. These are;
  1. Contact force
  2. Non-contact force/force field

Contact Force
