Inertia

 

  1. Definition- Inertia is the property of a body by which it continues to remain in its existing state of rest or uniform motion in a straight line unless an external force acts on it.

  • It is a dimensionless and unitless quantity.             

  1. Types of inertia:-

  • The inertia of rest- Inability of a body to change its state of rest by itself.

                          Ex- Person standing in the bus thrown backward when the bus starts suddenly.

  •         The inertia of motion- Inability of a body to change its state of motion by itself.

                          Ex- Person standing in a moving bus thrown forward when the bus stops suddenly.

  •  The inertia of direction- Inability of a body to change its direction of motion by itself.

                          Ex- The raindrops falling vertically downwards cannot change their direction of motion.
