|
|
kinetic Friction
|
|
|
both kinetic friction and air resistance

Explanation:
Detailed explanation-1: -friction is defined as the opposing force between two sliding objects.
Detailed explanation-2: -The force of gravity (also known as weight) acts in a downward direction; yet the normal force acts in a direction perpendicular to the surface (in fact, normal means “perpendicular").
Detailed explanation-3: -Rolling friction is friction that acts on objects when they are rolling over a surface.
