Question

1. Define the terms (a) static friction (b) sliding friction​

Answer 1

Answer:

Static friction is the friction that exists between a stationary object and the surface on which it's resting. Once the objects have already started moving, kinetic friction takes over.

The term sliding friction refers to the resistance created by two objects sliding against each other. This can also be called kinetic friction. Sliding friction is intended to stop an object from moving.

Answer 2

Answer:

Static friction is the friction that exists between a stationary object and the surface on which it's resting. Once the objects have already started moving, kinetic friction takes over.

and for the other one, I dunno. hope it helps... somehow... I guess :)
