Why drag forces exist

Why objects fall at different rates due to drag forces

State the facts that affect the size of a drag force

Why friction exists

State the factors that affect the magnitude of friction

How to determine the direction of friction

Describe why some objects will not move when pushed

Describe how the size of a friction force changes as the size of the the parallel forces change
