Why does the air resistance increase as the speed does?

Best Answers

The increase in speed leads to an increase in the amount of air resistance. Eventually, the force of air resistance becomes large enough to balances the force of gravity. At this instant in time, the net force is 0 Newton; the object will stop accelerating. The object is said to have reached a terminal velocity. read more

A moving object has to push the air out of the way and transfer some kinetic energy to that air.You can feel this when you stand by the side of the road and a speeding car goes past.If the object moves faster it moves a greater mass of air per second and gives that air a greater increase of speed.Perhaps you could ask your students to make fans and then feel the effects of fanning themselves at different speeds. read more
