| Question | Answer |
|---|---|
| the energy of a body or a system with respect to the motion of the body or of the particles in the system. | kinetic energy |
| the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves through a distance of one meter in the direction of the force: equivalent to 10 7 ergs and one watt-second. Abbreviation: J, j | joule |
| physics, potential energy is the energy of an object or a system due to the position of the body or the arrangement of the particles of the system.[1] The SI unit for measuring work and energy is the joule (symbol J). | potential energy |
| potential energy that is stored when a body is deformed (as in a coiled spring) [syn: elastic energy] | elastic potential energy |
| chemical potential energy | Energy in the chemical bonds of matter.. |
| gravitational potential energy | he energy an object has due to its relative position above the ground. Found by mass x gravity (or gravitational field strength) x height |
| mechanical energy | Energy of the moving parts of a machine. Also refers to movements in humans. |
| law of conservation of energy | This law (also known as the First Law of Thermodynamics) states that energy can be converted from one form to another, but it cannot be created or destroyed. |
