Question

What role does friction play in the sport of cricket
Collect some pictures of that sport in action where friction is either supporting it or opposing it. Display these pictures with proper captions and write a report

Answer 1

Answer:

Supporting friction:

1) Cycling - the friction between the tires and the road are necessary for the bike to function

2) Running - the friction between the athlete's feet and the ground surface is necessary otherwise the runner would fall over

3) Swimming - the friction in the water is required for the swimmer to be propelled forward

Opposing friction:

1) Swimming - the friction makes it more difficult for the swimmer to swim very fast

2) Bobsleigh - the aim is to go as fast as possible but the friction between the bottom of the sleigh and the ice slows it down

3) Diving - the friction between the diver and the water creates wasted Kinetic energy and sound energy whereas the aim is to be as streamlined as possible
