Force can be defined as

Force can be defined as an effort that changes the state of motion or shape of an object. It can be a pull or push.

Force and its types

The quantity of force is expressed by the vector product of mass (m) and acceleration (a). The equation or the formula for force can mathematically be expressed in the form of:

F = ma

  • m = mass
  • a = acceleration

The standard international system of unit (SI unit) is expressed in Newton (N).

Types of forces

Force is a physical cause that can change the state of motion or the dimensions of an object. There are two types of forces based on their applications:

  1. Contact Force: Forces that act on a body either directly or through a medium are called contact forces.
  2. Non-Contact Force: Forces that act through spaces without making direct contact with the body are called non-contact forces.
