Electricity is the flow of from one place to another

Electrons

Explanation:

Electricity is the flow of electrons because all matter is made of atoms, and all atoms have a nucleus which contains positively charged protons, negatively charged electrons and neutrons with no charge. in the nucleus there are equal number of protons and electrons, but when there is a shift in this balance an atom may gain or loose electrons. when there is free movement of this electrons, current is constituted. therefore without the flow of electrons there would be no electricity.

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.
