Gravity
Gravity
Gravity (pronounced: /ˈɡravɪti/) is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) one another.
Etymology
The word "gravity" comes from the Latin word "gravitas," which means weight.
Definition
Gravity is the force that attracts two bodies toward each other, the force that causes apples to fall toward the ground and the planets to orbit the sun. The more mass an object has, the stronger its gravitational pull. This is known as the Law of Universal Gravitation.
