What is friction?Friction is the rubbing of

two surfaces. It is the force of two surfaces

coming in contact with each other.

You can make friction very

easily:

Rub your hands together.

Do you feel heat?

That is the result of friction.

We CAN, however, use some things to minimize

friction:•Oil (lubricant)•Ball bearings•Water•Polished metal (slide)
