Step-by-step explanation:
INERTIA - Inertia is the resistance of any physical object to any change in its position and state of motion. This includes changes to the object's speed, direction, or state of rest. Inertia is also defined as the tendency of objects to keep moving in a straight line at a constant velocity.
There are basically three types of Inertia-:
(a) Inertia of Rest: The inability of a body to change by itself its state of rest is known as Inertia of Rest.
Examples:
(i) Person sitting in a car falls backwards, when the car suddenly starts. It is because the lower portion in contact with the car comes in motion where as the upper part tries to remain at rest due to inertia of rest.
(b) Inertia of Motion: The Inability of a body to change by itself its state of uniform motion is known as Inertia of motion.
Examples:
(i) When a moving car suddenly stops the person sitting in the car falls forward because the lower portion of the body in contact with the car comes to rest whereas the upper part tends to remain in motion due to inertia of motion.
(ii) An athlete runs a certain distance before taking a long jump because the velocity acquired by running is added to the time of jump, so that it can cover a long distance.
(c) Inertia of Direction: The inability of a body to change by itself its direction of motion.
