Sports is useful because it makes you have a healthy life style and it keeps you fit, in a good mood and you won't get sick easily.
Friction is important for all sports.Without it it becomes really hard to accelerate or deaccelerate.For example a 100m sprinter.It would be great for him if there wasnt any air resistance (as long as he can breath).But he needs friction on the floor to push himself forward.however friction is less useful in hockey, skiing, and almost all types of boarding(snowboarding, wakeboarding, kneeboarding, sandboarding).
Useful is the actual production of electricity. Non-useful -- unused heat energy released into the environment.
There is not a sport in which friction is not useful. In hockey, for example, there seems to be no need for friction. However, in order to get moving or stand at all, the players rely of the friction between their skates and the ice. The friction between their skates and the ice also creates a thin layer of water while they skate, allowing them to glide over the ice. even chess relies on friction so the pieces do not move off the board.
I think a pulley is useful because it can help you and other people to.
Some useful inventions are the light bulb, wheel, and the telephone.
