Gravity is the force that gives weight to objects and causes them to fall to the ground when dropped. Two major factors, mass and distance, affect the strength of gravitational force on an object. You witness the first factor in everyday life - more massive objects are heavier.

That pull is gravity at work. Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects. You exert a gravitational force on the people around you, but that force isn't very strong, since people aren't very massive.

In general relativity, gravity is not a force between masses. Instead gravity is an effect of the warping of space and time in the presence of mass. Without a force acting upon it, an object will ...

The force of gravity is the weakest at the equator because of the centrifugal force caused by the Earth's rotation and because points on the equator are furthest from the center of the Earth. The force of gravity varies with latitude and increases from about 9.780 m/s 2 at the Equator to about 9.832 m/s 2 at the poles.

How does gravity affect acceleration? - Shareef Amer (age 11) Villa park IL. A: Shareef - Great question! And the answer is that, in a sense, gravity /is/ acceleration! You've probably heard of the "force of gravity," and you may have heard of the equation "F=ma." What this equation means is that the force on an object is the same as the mass ...

You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn’t really have an effect on our planet. Gravity in our universe. Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon ...

Gravity attracts objects that have mass and pulls them toward the center of the Earth. Everything on Earth is held by gravity including the atmosphere. On Earth, any object that has mass has gravitational pull; this is called force. Gravitational forces are forces of attraction.

Distance also affects the strength of the gravitational force. Therefore, the Earth has a stronger pull on us than Jupiter does, even though Jupiter is as big as over 1,300 Earths. While we are familiar with gravity's impact on us and on Earth, this force also has many effects on the entire solar system, too.

As for the science behind the action, we know that Isaac Newton defined gravity as a force -- one that attracts all objects to all other objects. We know that Albert Einstein said gravity is a result of the curvature of space-time. These two theories are the most common and widely held (if somewhat incomplete) explanations of gravity.

Everything about force of gravity is eloquently contained in the force equation: F=GMm/r^2, aka Newton's Law of Universal Gravitation. G is the Universal Gravitational constant So the variables are M, m, and r. M is one of the masses, and m is the...
