Gravity at Earth's Center
Gravity is a force of nature that pulls objects toward each other. It's important to understand gravity because it is a major part of everyday life. Gravity keeps you standing on the ground by pulling you toward Earth's center. Gravity gives you weight and causes objects to fall. Any object on or near Earth experiences the force of gravity.
In this video, you will learn more about how the force of gravity pulls objects toward Earth's center and how it changes the speed of a moving object. Watch the video to see how the acceleration caused by gravity would affect a person falling through an imaginary tunnel that passes through the center of Earth.
