Science chapter 4
|How are energy, work and, power related?
|Power= Energy Transferred / Time
|is he transfer of energy
|ability to do work or cause change (J)
|rate at which work is done
|What are two types of energy?
|kinetic and potential
|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
|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
