Question | Answer |
---|---|
Potential energy is | stored energy |
Kinetic energy is | energy of motion |
Potential energy is based on | position or chemical makeup |
Kinetic energy is based on | mass and velocity of the moving object |
The ability to do work is | energy |
The suns energy comes from which form of energy | radiant |
after eating a salad, Sue went outside to ride her bike. Sue riding her bike is what form of energy | mechanical |
After eating a salad, Sue went outside to ride her bike. The salad represents what form of energy | potential |
Fire is an example of what form of energy | chemical |
An electric blanket converts electrical energy to | thermal energy |
Power plants and stars are examples of | nuclear energy |
During photosynthesis plants converts radiant energy to | chemcial energy |
The transfer of thermal energy between substances of different temperatures | heat |
The ways that thermal energy is transferred | conduction, convection, radiation |
During a phase change the temperature will not | increase |
When you cook an egg on a frying pan, you are taking advantage of what type of heat transfer | conduction |
When you boil an egg, you are taking advantage of what type of heat transfer | convection |
As temperature increases what happens to the molecules in an object | the kinetic energy increases |
A glass on a shelf is an example of which type of energy | potential |
As the position of an object increases tht potential energy will | increase |
As the velocity and mass of an object increases the kinetic energy of that object will also | increase |
Thermal energy is lost when | energy changes forms |
A cat warming itself in the sun is an example of | radiation |
Molecules stop moving at | absolute zero |
The measure of the average kinetic energy of a substance | temperature |
