Answer:
By far, the Earth's gravity is greater than a human's.
The 'strength' of gravity depends on both of the objects being attracted by it.
Between any two masses, there is a pair of equal, opposite forces. The force of
gravity pulling you toward the Earth (your "weight") is exactly equal to the force
of gravity pulling the Earth toward you. If you weigh 150 pounds on Earth, then
the Earth weighs 150 pounds on you.
