Potential energy is the energy of _________.
Position, composition, shape, waiting, stored, and/or what the object is made of
Kinetic energy is the energy of _________.
motion and movement
What is mechanical energy? Give an example.
Energy of motion that includes all potential and kinetic energy. An example of mechanical energy is a train running along a track or a person juggling.
List the energy transformations for a person turning on a lamp.
mechanical-> electrical->light->thermal
1.Everything has _________ energy. 2. Any time an energy conversion takes place, some of the energy is converted to ________ energy.
1 & 2. Thermal
Potential energy depends on what two things?
distance and mass
Kinetic energy depends on what two things?
speed and mass
What is thermal energy? Give an example.
Thermal energy is the energy of heat. An example of thermal energy is a fire, an oven, or a lamp that heats when lit.
True/False. Energy can be created and/or destroyed.
False
List all the different types of potential energy.
gravitational, elastic, chemical, electric
List all the types of kinetic energy.
Mechanical, thermal, electrical, light (electromagnetic), sound, nuclear,
What is electrical energy? Give an example.
Electrical energy is energy generated by a power plant or other source which travels in currents (negative charges). Electrical energy comes into schools, houses, and businesses, and objects like microwaves, computers, TVs, etc. use electrical energy to work.
True/False. Speed makes a greater impact than mass on an object's kinetic energy.
True
What two kinds of potential energy does an energy drink in a vending machine have and why?
Chemical-b/c it can be consumed and used as energy. Gravitational- b/c it can fall.
What two types of energy does a hairdryer emit and why? (hint- not electrical)
sound- b/c it makes noise thermal- b/c it creates heat
What is light energy? Give an example.
Energy that can travel through empty space in the form of electromagnetic waves (produced by vibrations of electrically charged particles). An example of light energy is electromagnetic rays from the sun reaching Earth.
_______ type(s) of energy can transform into ______ type(s) of energy. a. some/some b. some/any c. any/any d. any/some
c. Any/any
Pick one of the types of potential energy and list 3 different examples for that type.
Did you give three good examples of your potential energy type?
Pick one of the types of kinetic energy and list 3 different examples for that type.
Did you give three good examples of your kinetic energy type?
What is nuclear energy? List and define both types.
Nuclear energy is energy that is stored in the nucleus of an atom (change made to the nuclei of atoms). Fission is where the nuclei of atoms are split apart and fusion is where the nuclei of atoms are forced together.
