What are the three types of inertia?

Back

1. Inertia of Rest 2. Inertia of Motion 3. Inertia of Direction

Front

What happens during inertia of rest?

Back

When a bus or train starts to move suddenly, the passengers sitting in it fall backward due to inertia of rest.

Front

What happens during inertia of motion?

Back

When a moving bus or train stops suddenly, the passengers sitting in it jerk in the forward direction due to inertia of motion.

Front

What is inertia of direction?

Back

Inertia of direction explains that rain drops cannot change their direction on their own, which is why we can protect ourselves from rain using an umbrella.
