Mr. Scanlan work, energy and power
| Question | Answer |
|---|---|
| What is done on an object when a force causes a displacement of the object? | Work |
| The energy of an object that is due to the object’s motion is called what? | Kinetic Energy |
| This variable depends on speed and mass. | Kinetic energy |
| 1/2 the mass x velocity (squared) equals what? | Kinetic Energy |
| The energy associated with an object because of the position, shape, or condition of the object is called what? | Potential Energy |
| The potential energy stored in the gravitational fields of interacting bodies is called what? | Gravitational Potential Energy |
| This variable depends on height from a zero level. | Gravitational Potential Energy |
| This is the energy available for use when a deformed elastic object returns to its original configuration. | Elastic Potential Energy |
| The symbol k, a parameter that measures the spring’s resistance to being compressed or stretched is called what? | Spring Constant |
| The sum of kinetic energy and all forms of potential energy associated with an object or group of objects is called what? | Mechanical Energy |
| This a quantity that measures the rate at which work is done or energy is transformed. | Power |
| work ÷ time interval | Power |
| force x speed | Power |
| Mass x gravitational pull x height | Gravitational Potential Energy |
| 1/2 spring constant (K) times distance (X) squared | Elastic Potential Energy |
