Define the property inertia and mention and define the 3 types of inertia as well.

Author: ok



Answer:

Inertia is the property of a body to remain in its state of rest or motion and resist change. Inertia depends on the mass of the body and is directly proportional to it, i.e, it increases or decreases with an increase or decrease in mass of the body. There are 3 types of inertia 1- the inertia of rest 2- the inertia of motion 3- the inertia of direction. 1: Inertia of rest states that a body at rest will continue to be at rest until an external force is applied to it. 2:iinertia of motion states that a body in motion will continue to be in motion until an external force is applied to it. 3: Inertia of direction states that a body moving in a particular direction will continue to move in that direction unless a force is applied to it to change its direction.
