Part 1: Answer the following questions Name AND describe the components needed to make a complete circuit.

Compare and contrast a series and parallel circuit. Give at least one way that they are similar and one way they are different.

Similarity:

Difference:

Ohm’s Law is represented by the equation I = V/R. Explain how the current could change if the amount of resistance decreased and the voltage stayed the same.

Define resistance.

Describe what would happen to the resistance if the voltage increased but the current stayed the same.

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.
