Answer 1

Explanation:

Inertia: The inherent property of a body by virtue of which it cannot change its state of rest or of uniform motion until unless a force acts on it.

Three types of inertia:

Inertia of rest: The tendency of a body to remain in its position of rest is called inertia of rest.

Example: While standing in a bus, we fall backward if the bus starts suddenly.

Inertia of motion: The tendency of a body to remain in its state of uniform motion in a straight line is called inertia of motion.

Example: When a running horse stops suddenly, the person sitting in it falls forward.

Inertia of direction: The inability of a body to change its direction of motion by itself is called inertia of direction.

Example: When car takes a sharp turn, a person sitting in the car experience force, acting away from the centre of the curved path. This happens, due to the tendency of a body to hold its original direction.

Answer 2

Answer:

Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.
