Matter causes gravity in the first place.
Gravity is NOT matter, it is a force that effects matter.
No. Mass causes gravity, and it can be measured bythe effects of gravity, but mass also has other effects - especially, inertia. Mass is often explained as the "amount of matter". Please note that this is an informal, and not very precise, definition - but it may help you understand what it is about.
what are the effects on Gravity Bongs? What do they do, and what do they feel like?
No. Gravity is a consequence of matter but it does not have mass itself.
It is not a matter of chance it is a matter of physics. The moon is tidally locked with the earth. All this takes are the effects of gravity and time.
gravity and how mass is effected by it
Dark matter and Light matter. They are tweakable, anti-gravity materials. Dark matter and light matter have the same effects but just look different. Very useful for creating floating platforms so it is best to use them in a platformer.
The force with which gravity pulls on a quantity of matter is referred to as gravity.
It guarantees that no matter how many engines your rocket has, or what direction you launch it, it'll always end up on the ground.
Gravity is produced by all matter, including that of Earth.
