| Question | Answer |
|---|---|
| Energy stored in an object. | Potential Energy (PE) |
| Energy of motion or action. | Kinetic Energy (KE) |
| Energy of an object above the Earth. | Gravitational Potential Energy [GPE] (Joules) |
| Gravitational force exerted on an object. | Weight (Newtons) |
| Amount of matter in an object. | Mass (Kilograms) |
| 9.81 m/s squared the acceleration of objects in free fall. | Gravity (m/s squared) |
| How high the object is above the reference heigth, usually the ground. | Height (M) |
| Energy of an object in motion. | Kenetic Energy (Joules) |
| Speed of an object in a direction. | Velocity (V) |
| -Energy of a system due to position or motion. | Mechanical |
| -The sum of the KE of all the particles of an object. | Thermal |
| -Transmission of Energy by a wave in a specific direction. | Acoustic |
| -Energy from the excess the lack or the movement of e-. | Electrical |
| -The ability to do work through the influence of a magnetic field. | Magnetic |
| -Electro magnetic waves radiated by maqtter (EM). | Radiant |
| -Potential stored in chemical bonds. | Chemical |
| -Energy stores (PE) in aton's nucleus that is released in nuclear fission and fusion. | Nuclear |
| -Energy found in matter. | Mass |
| Energy can never be created or destroyed, only changed from one form to another. | Law of Conservation of Energy |
| As a system approaches absolute zero, all processes cease and the entropy of the system approaches a minimum value. | Third Law of Thermodynamics |
