Gravity
Three types of scientific categories that makes life.
Gravity
Gravity or gravitation is a natural phenomenon by which all things with energy are brought toward (or gravitate toward) ...
Energy
Transferred to other objects or converted into different forms. The "ability of a system to perform work" is a common description, but it is misleading because energy is not necessarily available to do work.
Motion
Motion is one of the key topics in physics. Everything in the universe moves. It might only be a small amount of movement and very very slow, but movement does happen. Don't forget that even if you appear to be standing still, the Earth is moving around the Sun, and the Sun is moving around our galaxy.
