It changed the world by making scientist look different upon the world
Not sure what you mean by "change gravity"; a nebula has mass, therefore it exerts a gravitational force.
gravity can change the motion of an object because of magic
he found gravity the thing that makes us not float off into space
knowing about gravity can have much impact to improve the gravity system. the gravity system involves almost all physic knowledge. starting from the formula of the first newton and second and the third. gravity can help us with our balance in second place after our ears.
There is no anti gravity point in the world, the whole of Earth has gravity.
weight
Gravity does not keep the world up!
A world without gravity is not a world; it is barely enough to be more than just a rock in space.
Yes. As acceleration due to gravity increases so does the object's weight. The reverse is true when gravity decreases. Mass, however, does NOT change with gravity.
No, it gives you weight. Mass does not change in the presence of gravity.
As compared to Earth, you mean? If an object doesn't change its shape, the center of mass doesn't depend on gravity - and the center of gravity hardly does so.
no
