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 |
