- Gravity is an attractive force that pulls two objects toward one another. Gravity is stronger coming from heavy objects when compared to light objects. The force of gravity weakens as the distance between objects increases.
- All objects in the universe feel the effects of gravity. Us humans feel the Earth’s gravitational pull towards its center. The Sun, which is larger than the other planets, pulls all of them toward itself, and each planet pulls back against the Sun. Since they are much smaller than the Sun, their pull is much weaker.
- Humans have a gravitational pull toward other humans, but it is weak and not noticeable. Therefore, the force of gravity diminishes with the decrease in size.
The force due of attraction between two bodies is proportional to the mass of both objects but inversely proportional to the square of the distance between them.
