Question

Which type of force is one of the greatest enemies of athletes in the Olympic Winter Games? In what other situations does this force exist outside of the world of sports?

Answer 1

It is frictional force.
This force exists everywhere outside the world of sports. It opposes the motion of one body over the other.

Answer 2

If your taking this on edmentum the sample answer is

Drag, or atmospheric resistance, is one of the greatest enemies of athletes in the Olympic Winter Games. Drag is a kind of friction that opposes athletes' movements through the air and slows them down. However, drag doesn't just affect athletes; it acts on any object moving through the air. I’ve noticed the effects of drag on cars. Newer cars with aerodynamically shaped fronts are less affected by drag than older cars with large, flat fronts. An aerodynamic shape reduces the drag by curving the air around the body of the car. The same principle applies to other vehicles too. For motorbikes, airplanes, and even ships, engineers try to design a shape that will keep drag at a minimum.

So you might want to change this into your own words but I hope this is of help ❤️❤️
