Thermodynamics
Definition of a conductor
An object that allows heat to transfer through itself easily
Type of PE you gain from height
Gravitational potential energy
Energy of movement
Kinetic energy
Mechanical energy is
KE+PE in a system
Type of heat transfer associated with cold, dense air and warm, less dense air
Convection
Definition of an insulator
An object that does not allow heat to transfer through itself easily
Type of PE associated with a stretched rubber band
Elastic PE
Kinetic energy equation
KE=1/2mv^2
You know the PE and the mechanical energy in a system. Find KE
ME-PE
Type of heat transfer associated with a pan and stove
Conduction
Definition of heat
Transfer of thermal energy from one place to another
Definition of PE
Stored energy/energy that has the potential to do work
What object has more KE:
A 10 kg object moving at 2 m/s
A 5 kg object moving at 4 m/s
The 5 kg object
Your mechanical energy is 50 J. You have 38 J of KE. Find your PE
12 J
Type of heat transfer associated with a campfire
