The word kinetic is derived from the Greek word for motion (kinesis), and the word energy is the ability to do something (energia). Kinetic energy, then, occurs from motion and the object in motion’s ability to do work. Kinetic energy can take three forms: rotational, translational, and vibrational. Rotational kinetic energy comes from its rotational motion, such as that produced from the spinning of the Earth on its axis. Translational kinetic energy is generated when an object moves from... więcej

Energy comes in many different forms. Some common forms of energy are thermal or heat energy, chemical energy, gravitational energy, and electrical energy. Kinetic energy is the energy an object possesses because of its motion. Any kind of motion produces kinetic energy, including translation (movement along a straight line), rotation, and vibration. Objects at rest have zero kinetic energy. The faster an object moves, the greater its kinetic energy.
