How does the force of air resistance depend on an object speed?

4vir4ik [10]

Answer:

The force of air resistance clearly depends on the velocity of an object moving through the air: the larger the speed, the larger the drag force.

Explanation:

As learned above, the amount of air resistance depends upon the speed of the object. ... Thus, more massive objects fall faster than less massive objects because they are acted upon by a larger force of gravity; for this reason, they accelerate to higher speeds until the air resistance force equals the gravity force.
