Q.6 Explain why sportsmen use shoes with spikes.

Answer :

Sportsmen use shoes with spikes to increase the friction between shoes' surface and the surface of the ground.

Because if the shoes are used without spikes during sports, then the shoes will have comparatively less roughness, and thus they won't get interlocked properly with the surface of the ground, making it difficult for the sportsperson to walk and run on the ground.

If there is no interlocking or less interlocking then the person may slip and injure themselves.
