Types of Inertia in Physics

Inertia in Physics:

Inertia is the property of a body by virtue of which it opposes the cause which changes or tends to change the state of rest or of uniform motion in a straight line of the body.

It is to be noted that the mass of a body is the measure of its inertia. The more the mass of a body, the more is its inertia.

Types of Inertia:

Thus, inertia can be classifed into two types –

  • Inertia of rest
  • Inertia of motion

Inertia of rest:

It is the property by virtue of which a body at rest tends to be in the state of rest.

Inertia of motion:

Inertia of motion is the property by virtue of which a body in motion tends to continue in motion with uniform speed along a straight line.
