What is free fall and what are its effects on objects on earth and in space?

Its when a body is allowed to fall towards another body, where gravity is the only force (or significant force) acting on the body - at least initially.
Near the surface of the Earth, an object in free fall (in a vacuum) will accelerate at approximately 9.81 m/s2, regardless of its mass. In air, air resistance will act against this force as the object velocity increases, the object will eventually reach a terminal velocity where the upward air resistance and the downward force of gravity balance out. Terminal velocity depends on many factors including mass, drag, relative surface area, and will only really come into play if the fall is from sufficient altitude.
In space, there is no air, so a body can keep accelerating under the force of gravity until it hits that body it is accelerating towards (or its atmosphere if its large enough to have one).

What happens to objects that fall from space towards earth?
they all fall back into space like gravity.
What space objects are made of chunks of rock?
Comets and asteroids are made of chunks of space rocks and dust. Meteorites are space rocks that are captured by the earth's gravity and fall to earth.
How objects fall on Earth and on the moon?
Objects fall faster to the earth, then compared to the moon, it is due to the different power of gravity on the the earth and moon.
If you removed air resistance would objects fall with constant acceleration?
Yes. Neglecting the effects of air resistance, all objects near the surface of the earth fall with the same constant acceleration, regardless of their mass/weight.
Why do most objects fall to the ground?
Most objects fall to the ground because of gravity. Gravity is a force, inside the Earth,that makes everything go down. Space has no gravity, so if a human went up there, they would float.
Why do you fall off in space?
No gravity to weigh objects down
If the Earth has 81 times the mass of the Moon then why don't objects 81 times smaller than our body's mass orbit us?
They could if you and the small objects were isolated in space. On Earth, those objects are much more strongly attracted to the Earth and would simply fall to its surface. Essentially, the Earth's gravitational field overwhelms our own.
What force makes objects fall to earth?
Gravity.
Why do objects fall towards the center of the earth?
Gravity
Is it possible for earth to fall?
no. gravity causes objects to fall. So unless the sun(earth's source of gravity) moves, then earth will not "drop"
Why people do not fall of earth while astronomers float in space?
Gravity on earth lack of it in space
What part of the Earth do objects fall toward?
ThE centre or core
