Question:
Give six advantages of friction.
Answer:
Friction is the opposing force which acts on a body while it is in motion inside the atmosphere of earth.
The friction has so many advantages which are mentioned below:
1. It helps us in walking.
2. The friction between the feet of animals and the ground make it easier for them to run fast.
3. The friction between the tires of cars and the roads helps the car driver to stop the car when brake is applied.
4. The friction between our pen and the notebook helps us in writing.
5. When meteors, etc. from space falls on earth then due to friction wear and tear is caused on them and they become smaller in size, hence reducing the destruction caused by them on earth.
6. The friction between the matchstick and the match box helps us in lighting the matchstick.
