GPE:
Formula
GPE (J) = m x g x h
(Mass, gravity-9.8, height
ο As an object rises itβs GPE increases
ο As an object falls itβs GPE decreases
Kinetic Energy
ο Kinetic energy depends on:
ο‘ Mass
ο‘ Speed
ο An object at rest has:
ο‘ No thermal energy
ο‘ No KE
ο Formula
KE (J) = Β½mv2
(mass, velocity)
ο Potential Errors
ο‘ Changing more than one variable
ο‘ Consistent measurements from the same point on the rod
ο‘ Human error-lack of consistency
ο Results
ο‘ Increasing the height and mass cause the nail to move further into the block
Energy Transfer and Transformation
ο Energy Transfer-energy moving from one place to another
ο‘ Ex: rod to the nail from activity 54
ο Energy Transformation-energy changing types
Ex: roller coaster
Changing GPE to KE
ο GPE and KE can change into one another
ο‘ Example
ο As an object falls it loses GPE and gains KE
ο Friction-rubbing of objects together
Law of Conservation of Energy
ο Energy isnβt created or destroyed, it transforms from 1 form to another
Heat and Temperature
ο Heat- Movement of thermal energy from hot to cold
ο Temperature-measure of the average kinetic energy
Thermal Energy
Formula
Change in THe = mc T
(mass) x (specific heat) x Change in Temp. (Final- initial)
ο Potential Errors
ο‘ Lack of consistent shaking speed and distance
ο‘ Lack of consistent vial hold or temperature reading location
ο Results
ο‘ Kinetic energy and increase of temperature are related
