Think of a car, friction causes air resistance on the car and results in lower gas mileage, but without friction, the tires would just spin in place and the car would not go anywhere.
it can hurt them because what if they were to fall they would get hurt and it would hurt more if they were on the top of a pyramid.
Ratchetgirl! :d
how does friction help car tyres?
No; friction decreases gas mileage.
by energy
they either help you or they can hurt you they either help you or they can hurt you
because you are using friction or fire
I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
wheels overcome friction
because of the friction created between the t-shirt and the nipples....
friction
no it does not
