heat or thermal energy
Energy can not be lost or destroyed, only transformed into a different form of energy. True or False
True
the energy that an object has because of its motion
kinetic energy
The energy of motion
kinetic energy
___________is when heat is transferend when there are no particles to carry the enrgy
radiation
this form of energy is used to cook food on a grill
thermal/heat energy
A light bulb converts electrical energy into what energy?
Light Energy
how did you use mechanical energy today?
your car, bike, scooter, bus, automatic door, any gears, chains or wheels
what is an example of convection?
heat rising, wind, boiling water, ect.
This type of energy is present when you pull on a rubber band
potential energy
explain conduction
conduction is when particles bump into each other transferring their heat to one another.
What kind of energy does a cart SITTING on the top hill of a roller coaster have?
potential energy
what is more conductive? plastic or metal
metal
the plastic spoon did not heat up the ice fast because it is an.... insulator or conductor?
insulator
which is a insulator, which is a conductor? wood, metal
metal is conductor, wood is insulator
why did the metal spoon heat up the ice cube faster
it is a conductor of heat. it can easily move energy
heat transfer that occurs when particles bump into each other but do not change location
conduction
total kinetic energy of the particles in a substance
thermal energy
what is heat?
the transfer of thermal energy
the energy that an object has because of its position or condition; stored energy
potential energy
How does ice cream melt in the sun?
thermal radiation energy from the sun heats up and melts the ice cream
