Question

In which case of running an athlete need more force running in the straight lines or running on a circular loop or what will be the change in style of an athlete running on the track give reason?

Answer 1

Answer:

an athlete running on

circular loop will be needing more force because running around the circle causes change in velocity and that leads to acceleration.For acceleration, force is required.

F=M×A

M is constant.

1. so, removing constant from above equation gives us,F is proportional to A,i.e. acceleration
