Kinetic energy
|
Energy of motion
|
|
|
Formula for Kinetic Energy
|
KE=1/2mv2
|
|
|
When do you have the most KE?
|
The more you jumped/moved around
|
|
|
Absolute Zero
|
When matter stops moving
|
|
|
Temperature
|
The measure of the average kinetic energy of the particles in an object
|
|
|
Thermal Energy
|
The total kinetic energy of an objec
|
|
|
When do you have the most thermal energy?
|
When you have a high temperture and more substance
|
|
|
Heat
|
The transfer of energy between objects that are at different temperatures
|
|
|
What are the 3 types of heat transfers?
|
1. Conduction
2. Convection 3. Radiation |
|
|
Conduction
|
Transfer of energy through matter by the direct contact of particles
|
|
|
Where does conduction best work in?
|
Solids, especially metals
|
|
|
Why are metals good conductors?
|
Because electrons move easily and transfer KE to nearby particles
|
|
|
Convection
|
Transfer of thermal energy by the movement or circulation of a fluid
|
|
|
Fluid
|
Any material that flows
|
|
|
What 2 forms can fluid be in?
|
Liquid or gas
|
|
|
Whats the difference between convection and conduction?
|
Conduction involves collisions and transfers of energy
Convection involves movement of the entergetic particles from one location to the another |
|
|
When can conduction and convection occur?
|
When matter is present
|
|
|
Radiation
|
A heat transfer through space as electromagnetic waves
|
