Because you wouldn't be able to move about without it.
Rubber bath mats are useful with friction because they have a lot of friction and can stop you from slipping because of all the friction it produces. - thank you to this website for the answers :)
Racing because friction slows you down but you need to go fast.
Yes, friction is useful because it helps to provide traction for walking and driving, prevents objects from sliding off each other, and allows us to grip objects. However, excessive friction can also lead to wear and tear on surfaces.
frictional is invaluable (extremely valuable) to everyone. it literally holds the word together.
Friction is useful because it provides traction for walking and driving, allowing us to move on surfaces without slipping. It also helps us to grip objects and manipulate them with our hands. Additionally, friction generates heat, which can be harnessed in machines for various purposes.
Brakes are meant to have a lot of friction and it's useful.
No Friction Runes Computers
the friction from pushing the hull through the water is not useful as long as you're travelling.
Friction converts mechanical energy into heat, which is rarely useful, and which can never be recovered in its entirety. Due to conservation of energy, this heat energy is not available for other things, i.e., for useful work.
It can be useful when a ball is catching
Yes, friction is useful because it can cause heat. Rub your hands together and notice that they will get warm. HEAT!!! Above: not from Marbles48. hehehe. Actualy, it is soo useful that it can be used for anything from launching a ball in to the air, to a rocket to the moon. i know because i have been in a friction-launched rocket to the g17 sector of the atmosphere! ask about g17 sector and I'll answer that for you too!

how does friction help car tyres?
