Gravity has been around as long as there has been mass. They come together; you can't separate them.
Gravity affects the bounce of a basketball because if there is gravity, the basketball will come back down after it bounces. But if there is no gravity, the basketball will bounce and travel indefinitely upwards and never come back down until a gravitational force pulls the basketball towards it.
Nothing, gravity affects everything in the universe every yocto-second. You cant come up with a non example. Even anti-gravity is an example of gravity since your just reversing the pull of gravity to a push.
No matter what happens what goes up must come down. For example if you jump up into the air you have to come down because of the force of gravity. Same for space travel. If you jump on the moon you must come down.
because of gravity
You don't specifically need a magnet to overcome the force of gravity; ANY force that is stronger than gravity can "overcome" it, at least temporarily. For example, if you lift an object up, you are "overcoming" the force of gravity.
You come up, you come down.
Its mass
The gravity that keeps the planets in orbit is the sun's gravity, which is a product of the sun's mass.

The force is gravity.
the mass of the earth exerts gravity on all objects around it
The blade of a gravity knife is contained within the handle of the knife. It requires a spinning motion or gravity for the blade to come out of the handle.
Gravity affects the bounce of a basketball because if there is gravity, the basketball will come back down after it bounces. But if there is no gravity, the basketball will bounce and travel indefinitely upwards and never come back down until a gravitational force pulls the basketball towards it.
Of those three questions, the only one that makes any sense is the last one. Gravity doesn't come from a place (the "Where" part) or a thing (the "What" part). Gravity is strongly suspected to have come into existence at the time of the Big Bang, along with the other three fundamental forces. If the Theory of Everything people are right, at extremely high energies the forces combine; gravity would probably have been the first to separate out, at about one Planck time after the Big Bang (a "Planck time" is about 5 x 10-44 seconds).
Gravity Falls came out the summer of 2014.Season 2 of Gravity Falls is expected to be out on August 1st.
