Question

collect some pictures of that sport in action where friction is either supporting it or opposing it

Answer 1

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 


hope it helps you

Thanks

Answer 2

Some sport in action where friction is either supporting or opposing it are as follows:

Supporting friction:

• Cycling: For a bicycle to move along a road, there must be friction between the tires and surface.
• Running: Without friction between the athlete's feet and the ground, the runner would trip and fall.
• Swimming: When swimming, the swimmer must be propelled forward by the friction in the water.

Opposing friction:

• Swimming: Swimming is more challenging when there is friction because it is more difficult to swim quickly.
• Bobsleigh: The goal of a bobsleigh is to travel as quickly as possible, but this is slowed down by friction between the sleigh's bottom and the ice.
• Diving: The goal is to be as streamlined as possible, but friction between the diver and the water wastes kinetic and sound energy.
• Tenpin Bowling and curling: These are two examples of rolling sports where friction is important. In tenpin, the ball's spin causes it to roll in an arc while also slowing it down due to friction resistance on the ball.
