I am an engineer building a new hair dryer. I have developed an efficient motor to move the air around, and filaments to heat the air as it passes through. However, when I test my hair dryer using different amounts of current, I find that the hair dryer overheats when current passes 13 amps. To ensure this is not dangerous for my customers, what should I install into my hair dryer? How does it work? Where would I install it?

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
