2. The transfer of thermal energy between touching objects is ____.
1. convection
2. conduction
A roller coaster at the top of a drop about to go down, it drops and it is moving down the drop.
(potential or kinetic energy)
When the roller coaster is going down the drop and moving it is kinetic energy. When the roller coaster is at the top of a hill about to go down it is gaining potential energy
wind
renewable resource
Metal wires in hot water making cold water warm up, holding a hot cup of coffee, metal spoon in a hot cup of coffee, egg frying in a pan is all an example of what.
Conduction
1. The energy that comes from the sun. Calculator is an example.
2. Radiation we see. The sun.
1. solar energy
2. light
1. The ability to cause changes in matter is ___.
2. The energy of motion is ___.
1. energy
2. kinetic energy
A boy is on a Pogo stick and he is in the air going up, then he drops down to the ground and repeats this over again.
When he is going up he is gaining potential energy and when he drop to the ground he is moving down so he has kinetic energy.
natural gas
nonrenewable resource
Cooking in the microwave, hot air balloon rising, hand above hot pan, and boiling water are all examples of what?
Convection
Energy stored in fuel/energy that can be produced by a chemical reaction. An example is a hand warmer.
chemical energy
1. Saving something so it doesn't get used up is ___.
2. Hydroelectric energy is an example of ___.
1. conservation
2. renewable resource
A car is on the top of a hill, the hill is very steep it waits at the top of the hill and suddenly it drops down the hill and drives all the way down the hill.
When the car is at the top of the hill it has that potential energy and when it is going down it has kinetic energy.
coal
nonrenewable resource
Warming your feet by the fire, warming your hands by the fire, are both examples of what?
Radiation
The combination of all the potential and kinetic energy which something contains. An example is a wind up toy where does it get its energy from?
This is Mechanical energy. The energy comes from the person winding up the toy because you are twisting the wind up and the energy is flowing to the wind up toy.
1. Energy that comes from the sun as heat and light is ___.
2. Energy released through a chemical reaction is ___.
1. solar energy
2. chemical energy
There is a book at the top of a bookshelf as it waits at the top of the shelf it falls down onto the ground.
when the book is at the top on the shelf it has potential energy and when it is falling to the ground it had kinetic energy.
water
renewable resource
Wrapping up in a blanket, holding a metal rod over fire, walking on hot sand are all examples of what?
Conduction
Energy that comes from an electric current such as a outlet.
Electric energy.
1. The energy of an object due to its condition or position is ____..
2. The transfer of energy in waves through matter and space is ___.
1. potential energy
2. radiation
There are 3 balls on the shelf, in this order:
A
B
C
Ball C is in the air but not B and A.
Ball A and B have potential energy and ball C has kinetic energy. Ball A has more potential energy because it is higher up.
1. oil
2. sun
