| Question | Answer |
|---|---|
| Reference Point: | A place or object used for comparison to determine if something is in motion |
| Distance SI Unit: | Meter (measures the length of a path between two points) |
| Power: | The rate at which energy is transferred, or the amount of energy transferred in a unit of time. Power= Energy Transferred/Time |
| Kinetic Energy: | The energy an object has due to its motion. |
| Potential Energy: | The energy an object has because of its position, also the internal stored energy of an object, such as energy stored in chemical bonds. |
| Gravitational Potential Energy: | The energy an object has because of its position, also the internal stored energy of an object, such as energy stored in chemical bonds. |
| Elastic Potential Energy: | The energy that can be associated with objects that can be compressed or stretched |
| Mechanical Energy: | The form of energy associated with the motion, position, and shape of an object. |
| Nuclear Energy: | The energy stored in the nucleus of an atom. |
| Thermal Energy: | The total potential and kinetic energy of the particles in an object. |
| Electrical Energy: | The energy of electrical charges. |
| Electromagnetic Energy: | The form of energy that travels through space in waves. |
| Chemical Energy: | The potential energy stored in chemical bonds. |
| Speed: | The distance an object moves per unit of time. |
| Average Speed: | Calculate the total distance traveled by the total time. (Speed= Distance/Time) |
| Instantaneous Speed: | The speed at which an object is moving at a given instant in time. |
| Velocity: | Speed in a given direction. If you know the speed and direction of an object, then you know the velocity. |
| Graphing Motion: | Plotting time on the x-axis (horizontal axis), and distance on y-axis (vertical axis). |
| Slope: | is the steepness of the line, shows how fast one variable changes in relation of the other variable. Slope= Rise/Run |
| Energy Transformations: | a change in energy from one to another. |
| Law of the Conversation of Energy: | Energy cannot be created or destroyed just changed from one form to another. |
