Question

What is Meant by Inertia?

Answer 1

1. Inertia is the property of a body that continues to be at its existing state of rest or of uniform motion in a straight line unless an external force is applied to it.
2. Newton's first law of inertia: An object will continue to be in the state of rest or in a state of motion unless an external force acts on it.
3. There are three types of inertia:
   3.1 Inertia of rest: When the resistance is offered by the body to continue in the state of rest unless an external force acts on it.
   3.2 Inertia of direction: When the resistance is offered by the body to continue the motion in the same direction unless an external force acts on it.
   3.3 Inertia of motion: When the resistance is offered by the body to continue to be in the uniform motion unless an external force acts on it.
