A person drops 2 objects from the same height. One object weighs 15 N, and the other weighs 10N. How does the mass of the objects relate to the force of gravity on them? 10n has more mass than 15n

10n has the same mass as 15n

15n has more mass than 10n

15n has twice the mass of 10n

another example of kinetic energy would be,

kinetic energy   >     moving energy

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.
