The Physics Classroom (870 words) |
 | Potential energy - the energy of vertical position - is dependent upon the mass of the object and the height of the object. |
| Kinetic energy - the energy of motion - is dependent upon the mass of the object and the speed of the object. |
| The work-energy bar charts for the coaster car illustrate that the car's energy is transformed from potential to kinetic and vice versa; yet the total amount of mechanical energy remains the same during the course of the motion. |
| The Physics Classroom (1266 words) |
| As kinetic energy is decreased (due to the object slowing down), the potential energy is increased (due to the stretch/compression of a spring or an increase in height above the earth). |
| The transformation (and conservation) of mechanical energy was the focus in the "Energy of a Pendulum" lab performed in class. |
| Conservation of energy on a roller coaster ride means that the total amount of mechanical energy is the same at every location along the track. |
