Gravity has been around as long as there has been mass. They come together; you can't separate them.
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.
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.
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.
Objects that go up always come down due to gravity, which is the force that brings objects back towards the Earth's surface. When something is thrown upwards, gravity acts as a constant force pulling it back down until it reaches the ground. This phenomenon is known as projectile motion.
well lets seeEXAMPLES: 1. we are still on the ground and not floating 2. it helps everything come back down like if u threw a ball to some one it would come back down but if u threw it and didn't come back that's because of no 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.
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).
