Examples of Inertia in Daily Life

Inertia is a concept in Physics that is defined as the tendency of an object to resist a change in its motion. In other words, Inertia acts as a resistance to any change in the velocity of any physical object.

What is Inertia?

Inertia is defined as the force which keeps stationary objects to stay still (remain at rest) or moving objects in motion at the same speed and in the same direction unless it is stopped by an external force. It can also be defined as the resistance of an object to resist change by remaining in its state of rest or in motion.

Law of Inertia and Newton’s First Law of Motion

The concept of inertia lies in Newton’s first law of motion, which is also termed as the “Law of Inertia.”

According to this law, an object will continue to be in a state of rest or in a state of motion unless an external force acts on it.

Let’s look at an example to understand the concept of inertia in a better way.

Let’s say a person is pedalling a bike and suddenly hits the front brakes. In this case, his/her body continues to move, and they fly over the handlebars. Here, the force applied on the front brakes acts as an external force.
