Energy, Work, & Power, (1 of 31) Kinetic Energy, An Explanation

Explanation of kinetic energy, the units and the relationship of the kinetic energy of an object to its mass and velocity. Kinetic energy is the energy that an object has due to its motion. It is defined as the work needed to accelerate an object from rest to a specific velocity. The same amount of work must be done on the object to bring it from the given velocity back to rest. Kinetic energy is directly proportional to the mass of the object and the square of its velocity. The SI unit for kinetic energy is the joule. Gravitational potential energy is the energy that an object has due to its position relative to other objects. Potential energy is often referred to as stored energy. Gravitational potential energy is dependent on the mass of the object, the acceleration due to gravity (9.81 m/s2) and the change in height of the objects. The SI unit for kinetic energy is the joule You can see a listing of all my videos at my website, http://www.stepbystepscience.com Link for sharing this video:    • Energy, Work, & Power, (1 of 31) Kinetic E...   Support my channel by doing all of the following: (1) Subscribe, get all my physics, chemistry and math videos (2) Give me a thumbs up for this video (3) Leave me a positive comment (4) Share is Caring, sharing this video with all of your friends
