Combing fine hair
Person walking on rug
Heat
E transferred in transmit of a hot to cold object
Hot plate heating water
Hot water cooling to room temp
Light
E transferred by the rapid movement of electro-magnetic fields
Sunlight
X-rays
Tv
Sound
E transferred by the vibration of an object
Voice under water
Music in air
Voice in mic
Electricity
Movement of charge and energy from one place to another
Lightning
Electricity through wires
Energy
The ability to move something somewhere
Potential energy
GPE
Heat vs temperature
Heat - type of KE that flows from hot to cold , causes change in temp , and is in Joules
Temp - measurement of avg motion of molecules in a substance , affected by transfer of heat, and measured in F and C.
How does a thermometer work
Outside - person -> liquid in therm , absorbs heat E , molecules speed up and expand, move apart which causes liquid to rise
Inide-
Liquid in therm -> cold water
Releases heat E , molecules slow down contract or move closer cause the liquid in the therm fall.
Potential Energy Examples
elastic,chemical,gravitational, and satic nuclear
All examples of Kinetic Energy
Heat,light,sound,eletricity
What type of energy is the buildup of stored electrons or ions
Electrostatic energy
What type of energy is a following is a movement of charge?
Electric current energy
What is the LOCE
Energy cannot be created nor destroyed but it can change from one type to another.
A roller coaster car slows to a stop because
The energy in the car transfers to the track and air
Energy star appliances
Uses less energy because they are quieter and more well insulated
Create a T-chart to compare heat and temp
Heat
-Joules
-causes change in temperature
Type of KE when heat goes to cold
Temp
-affected by transfer of heat
-Measurement of average motion of the molecules in a substance
-FºCº
As the number of windows in a home increases
The efficiency decreases because heat energy can transfer through the windows.
What lightbulb is 80%
Compact fluorescent light bulbs
