static friction
Sliding Friction
Sliding Friction
heat friction
Different materials have different coefficients of friction because the materials have different microscopic bumps and valleys which cause the friction to begin with. Coefficients of friction are constant for each material.
Sliding Friction
sliding friction
air resistance is different from friction because friction is more than one thing because there is many different types of friction air restance is one of those types of friction.
This kind of friction is referred to as drag, or air resistance.
Sliding friction requires more force to overcome its friction.
