Question
The tires of the vehicles get heated up after they move on the road for some time. The reason behind this is the _____.
- Conversion of potential energy into heat energy
- Absorption the heat from the atmosphere
- Friction between the tires and the road
- Conversion of mass into energy
Hint:
The tires of the vehicles get heated up after they move on the road for some time because of the friction between the tires and the road.
The correct answer is: Friction between the tires and the road
- Heat is an effect of friction.
- When the vehicle is moving on the road for a long time, it will get heated.
- This is because the friction between the tire and the road opposes the relative motion between the tires and the road.
