Without friction, your shoes would have no grip on a slippery field, increasing your chances of slipping over on wet grass.

Decreased friction is very helpful in working machinery, because friction causes wear and tear.Mainly its very helpful in moving parts. Decreased friction is also helpful in electric cables and wires, as reduced friction reduces energy loss via heat.
On a car, friction is useful on the tyres and brakes. It is not required for the parts that rotate.

That question doesnt exactly make sense, but if you meant HOW does friction and gravity AFFECT a soccer ball, the friction of the grass and ball affects the speed, and the gravity pushes the ball down to the ground. Hope it helped! -Cara

Friction can be helpful and not helpful it is not helpful when you are running because it slows you down hope that'll help!!!! ;)
Friction is in the grass. Friction slows the ball down.
Friction is helpful between car tyres and roads for grip. It is also sometimes used for heating as friction generates heat.

All friction affects a moving object, the source of the friction and the object moving is irrelevant. Water on a soccer ball would effect the performance of the ball.
The force of friction stops the soccer ball

Friction is necessary for wheels to rotate and nails to keep in walls.
Without friction, we couldn't walk or grip onto anything.
