Gravity

Gravity

What is it?

Gravity is the
force exerted by massive objects on other massive objects over a distance. The closer the objects are to each other, the stronger the force of gravity becomes.

Give me an example!

Have you ever noticed that when you throw a ball, it always comes back to earth? That's because the force of gravity works on the ball from the time it leaves your hand until it overcomes the other forces working on the ball and drives it back to earth.
