Question

what is force responsible for wearing out of bicycle tyres? ​

Answer 1

Frictional force.

• When the surface of one object comes in contact with the surface of another object the force will produce between them is called friction force.
• Friction is the force that resists motion between both surfaces.
• In the case of the bicycle, the tyres of the bicycle always come in contact with the road surface.
• Therefore when we drive a bicycle the friction force will produce between the bicycle tyres and road surface. therefore this force will resist the motion due to which the tyres of the bicycle will wear out.

Hence, The frictional force is responsible for wearing out of bicycle tyres.

Answer 2

Answer:

1. Frictional force between the tires and the ground results in the wearing out of bicycle's tyres .

2. In cycling, the rear wheel moves by the force communicated to it by pedaling while the front-wheel moves by itself.

3. So, while pedaling a bicycle, the force exerted by a rear-wheel on the ground makes the force of friction act on it in the forward direction (like walking).

4. Air resistance is caused by the frictional forces of the air against the vehicle.

5. The faster the vehicle moves, the bigger the air resistance becomes.
