Document Summary
Newton"s universal law of gravitation: the force of the two objects depends on the mass of both objects (i. e. you and the. Earth the force between these two is strong as the mass of earth is large. The force between two people is not as strong because the masses are smaller. : the force of gravity depends on the distance of the two objects as well. The gravitational force of pluto and the sun is much smaller than the force between. Mercury and the sun is stronger as mercury is closer than pluto to the sun: the force of the objects also affects the speed of the planets. The closer the planet is to the sun, the faster it will spin as the force is greater. The planets that are further away move slower because the force from the sun is weaker. Freefall: earth is applying a gravitational force pushing you down.
