Force: Meaning; Types and Uses of Force
<h1><strong>MEANING AND TYPES OF FORCE</strong></h1> CONTENT <ol> <li>Definition of Force</li> <li>Mathematical Expression of Force</li> <li>Types of Forces</li> <li>Differences between Gravitational Force and Magnetic Force</li> <li>Uses of Force</li> </ol> <h2><strong>Definition of Force</strong></h2> 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. <strong>Force is measured in Newton.</strong> <h2><strong>Mathematical Expression of Force</strong></h2> F ά mass × acceleration F = ma, where m = mass and a = acceleration due to gravity <h2><strong>Types of Forces </strong></h2> There are two types of force. These are; <ol> <li>Contact force</li> <li>Non-contact force/force field</li> </ol> <h3><strong>Contact Force </strong></h3>
