lesson 1
| Term | Definition |
|---|---|
| How are energy, work and, power related? | Power= Energy Transferred / Time |
| Work | is he transfer of energy |
| Energy | ability to do work or cause change (J) |
| Power | rate at which work is done |
| What are two types of energy? | kinetic and potential |
| Kinetic Energy | the energy an object has due to its motion |
| What is the formula for kinetic energy? | 1/2 x mass x speed2 |
| the faster the object | more kinetic energy |
| Potential Energy | energy that results from the position or shape of an object |
| Gravitational Potential Energy | potential energy related to an objects height |
| What is the formula for gravitational potential energy? | weight x height |
| Elastic Potential Energy | is the energy associated with objects that can be compressed or stretched |
