Overview

Force is a push or pull applied on a body by another body to change its state, size, or shape. It can change motion, stop motion, start motion, or deform an object. Force is measured in newton in the SI system and dyne in the CGS system. Force is the basic idea behind motion, turning effect, equilib

Key Concepts

Force is a push or pull

Force is a push or pull that can change the state, size, or shape of a body. It may change dimensions by stretching, compressing, or deforming an obje

These forces act only when objects

These forces act only when objects are in physical contact. Examples include frictional force, normal reaction force, tension in a string, force in a

These forces act without physical contact

These forces act without physical contact between bodies. Gravitational, electrostatic, and magnetic forces are non-contact forces. They follow invers

The CGS unit of force

The CGS unit of force is dyne and the SI unit is newton. One dyne gives an acceleration of 1 cm/s^2 to 1 g mass. One newton gives an acceleration of 1

A body remains in its present

A body remains in its present state until an external force acts on it. This is also called the law of inertia.

Learning Objectives

  • Understand the meaning of force and its effects on bodies
  • Differentiate between contact and non-contact forces
  • Learn the SI, CGS, and gravitational units of force
  • Understand Newton's three laws of motion and the equations of motion
  • Study moment of force, couple, and equilibrium
