Question

Explain why sportsmen use shoes with spikes.

Answer 1

Step 1: The purpose of wearing spiked shoes

1. Spikes increase friction by roughening the surface of the shoes.
2. This increases your ground grip and decreases your risks of slipping.
3. It becomes easier for athletes to walk or run when their grip on the ground improves.

Step 2: Factor affecting frictional force

1. The frictional force depends upon surface abrasion.
2. When the surface is rough, the frictional force is large; however, when the surface is smooth, the frictional force is low.
