You are on in line skates at the top of a small hill. your potential energy is equal to 1,000.j. the last time you checked, your mass was 60.0kg. ?

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.

there are no contact forces mentioned on the list of choices that you've provided.

technology is the application of the knowledge gained by science.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
