Ms. smith challenged his students to create an electromagnet that will pick up more paper clips than anyone else in the class. Timmy is very excited and beginning to collect all of the necessary materials. He finds a D cell battery, and iron nail, and a large role of cooper wire. what could timmy do, using just these materials, to increase the strength of his electromagnet to pick up the maximum amount of paperclips?

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.
