the friction from pushing the hull through the water is not useful as long as you're travelling.
Brakes are meant to have a lot of friction and it's useful.
Rowing a boat increases friction. The oars create resistance against the water, which generates friction that helps propel the boat forward.
No Friction Runes Computers
It can be useful when a ball is catching
how does friction help car tyres?
Sandpaper is high in friction but is not considered useful in terms of being helpful in a general sense.
stopping cars Friction is useful to start a fire with sticks.
It is 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).
No, it is not. Rolling friction occurs when a round object rolls across a surface. A boat on the ocean is not in contact with any solid surface. Instead of rolling friction the boat is subject to drag.
The brakes! And the tires (no friction = no traction).
there is friction in your cars brake system and without that frictiuon there your car would roll away whenever it was on a hill so this is a good example of when friction is useful.
