Hey, how you doing?

(You can trust this answer because i want to be an astrophysicist when i grow up!)

Answer

Astro= observation of celestial objects, physics= study of natural phenomena, and the mathmatics describing them. astro+physics= study of the physics describing celestial phenomena.

Physics (study of mathematics describing natural phenomena)

electromagnetism (study of electric and magnetic fields as well as light)

chemistry (study of molecules and atoms)

thermodynamics (study of energy [mostly heat energy])

ALSO

astronomy (observation of celestial objects)

Hope it helped (hope it made sence even more than it helped)

answer; /// the above statement is (true);

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.
