Yes, and no.

Friction IS useful to swimmers, because without friction, there would be no viscosity, and without viscosity, when the swimmer jumped in the pool, they would literally fall through the water to the bottom of the pool (just like you fall through air). Worse, without friction, they could not swim - and thus could not use the water to propel themselves upward to the surface. Unless a swimmer's body is buoyant enough, they might rest at the bottom of the pool until they drown. A swimmer could jump from the pool's bottom, and hope their buoyancy lets them reach the side of the pool, or to reach something to hang on to, but they could not swim to safety.

Friction is NOT useful to swimmers, because friction causes drag, and drag slows down the swimmer, and drag also forces the swimmer to expend more energy.

Where is friction not useful and how to reduce it?
Friction is not useful to most athletes (i.e swimmers, skiers, etc.) and friction is caused by the little imperfections and textures of objects against each other. You can reduce it by smoothing down one of the surfaces; like putting a very fine, smooth surface, or fabric over the skin of a swimmer to reduce friction.
Is one way that friction is useful?
stopping cars Friction is useful to start a fire with sticks.
Is friction useful?
yes friction is very useful because it help objects not to slide or slip
What three ways can friction be useful?
friction is useful for: you to walk It is needed for braking Can be used to produce heat
When is high friction useful?
High friction is useful for lots of things, like a goalkeeper's glove. The more friction there is between the glove and the ball, the easier it is to get a hold of it.

Describe 3 examples where low friction is not useful?
Friction is very useful but it has its own disadvantages. Friction causes wear and tear. Friction spoils the soles of our shoes. friction reduces speed This is all wrong some not useful types of friction are are when airplanes fly the friction causes heat that materials that will withstand which are costly.
Does brakes on a bicycle have a lot of friction or not much and is it useful or not useful?
Brakes are meant to have a lot of friction and it's useful.
Is one way that friction is useful?
stopping cars Friction is useful to start a fire with sticks.
Is friction useful?
yes friction is very useful because it help objects not to slide or slip
Is friction useful with computers?
No Friction Runes Computers
When can friction not be useful in a boat?
the friction from pushing the hull through the water is not useful as long as you're travelling.
What three ways can friction be useful?
friction is useful for: you to walk It is needed for braking Can be used to produce heat
When is a high friction useful?
It can be useful when a ball is catching
Why are tyres useful friction?
how does friction help car tyres?
When is high friction useful?
High friction is useful for lots of things, like a goalkeeper's glove. The more friction there is between the glove and the ball, the easier it is to get a hold of it.
When Is Friction Useful and When Is Friction Not Useful?
Friction is useful when you are trying to stop a car, but not useful in the pistons of a car's engine (It makes them less efficient).
