Energy Transfer - Coggle Diagram
Energy Transfer
Forms of Energy
Potential
Stored energy based on relative position in a system
PE=mgh
Kinetic
Energy object has by being in motion
Any body in motion has KE
KE=(1/2)mv^2
Units
Joules
(kgm^2)/(s^2)
Internal
Energy associated with random, disordered motion of molecules
Symbol
U
U = Sum of KE + Sum of PE
Sum KE
Random chaotic motion of molec and atoms
Sum PE
Interaction between atoms and molec
Delta U = Q(Heat) + W(Work
Work
E transfer when object moved over distance by external force
Work = Force x Displacement(Distance)
Relation w/ Heat
Heat released
Work is being done BY system
Heat Absorbed
Work is being done ON system
Symbol
W
Heat
E transferred from one body to another due to diff in temp
Symbol
Q
Energy Balance
Based on Law of Conservation
Energy In - Energy Out = Energy Accumulation
Energy in = Energy out
Law of Conservation of Energy
Energy can be created nor destroyed
Energy can only be transformed from one form to another
