Question

Name the two kinds of inertia.

Answer 1

(a) Inertia of Rest: The ability of a body maintain its state of rest is known as inertia of rest.

For example: When we shake the branch of a tree, the leave or the fruits fall down because the branches come in motion whereas the leaves or the fruits tend to remain at rest and hence get detached.

(b) Inertia of Motion: The ability of a body to maintain its state of uniform motion is known as inertia of motion.

For example: An athlete runs a certain distance before taking a long jump so that he can cover a long distance.
