Question

What is inertia? What gives the measure of inertia?

Answer 1

Mass is that quantity that is solely dependent upon theinertia of an object. The moreinertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

Answer 2

Hii dear,

# Inertia-
- It's property of the body that resist changes in its motion.
- That is, a body at rest will remain at rest and a body with constant speed will keep moving.

# Measure of inertia-
- There is no direct measure for inertia. But, certainly mass is directly proportional to inertia.
Inertia ∝ mass
- Also in rotational motion,
Inertia ∝ (radius of rotation)^2.

Hope, that helps you...
