Friction
What role does friction play in the spot of your choice? Collect some picture of that spot in action where friction is either supporting it or opposing it. Prepare a collage by using these pictures with proper caption.
Answers
Explanation:
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
Take any picture of any motion and make the collage as every motion exists on rough surface and every surface on earth is rough only or take from Google
