... Once this limiting friction is exceeded, sliding starts. ● There is also friction whenever an object moves through a fluid (liquids and gases). ● For example, when a car is travelling fast or a parachutist is falling through the air, there is an opposing frictional force called air resistance. ● Air ...

... • When an object falls toward Earth, it is pulled downward by the force of gravity. • However, a friction-like force called air resistance opposes the motion of objects that move through the air. • Air resistance causes objects to fall with different accelerations and different speeds. ...

... Unit 3 begins the study of the causes of motion (dynamics). An unbalanced force is one cause of motion. “Normal-sized objects moving at normal speeds,” keep our atudies in the realm of Newtonian physics. Newton's three laws are quite powerful and elegant and explain how an object moves when acted on ...
