Imagine that friction has disappeared from the earth. What will happen? Explain.

When friction will disappear from the Earth, the following things will happen:-

1. The brakes of the vehicles won’t work and the vehicles won’t run as the driving moving force is friction, the engine gives the rotating power to the wheels, the friction makes the car move forward.

2. We won’t be able to walk because we walk when we apply force on the ground backward and the ground applies it’s friction force forward, hence we walk.

3. We won’t be able to pick objects as the weight of the objects pulls it downward and the friction counter balances the weight and we are able to hold objects.

4. We won’t be able to write with pencil. As we write on paper due to friction the pencil graphite gets traced on the paper etc.
