Here is you answer mate

Explanation

Friction is a force that opposes motion between any surfaces that are touching. Friction can work for or against us. For example, putting sand on an icy sidewalk increases friction so you are less likely to slip. On the other hand, too much friction between moving parts in a car engine can cause the parts to wear out.

Wear and tear is damage that naturally and inevitably occurs as a result of normal wear or aging.

For example, repeated impacts may cause stress to a hammer's head.
