What are the two most common types of Potential energy?

Gravitational and elastic.

100

What is the difference between kinetic and potential energy?

energy in motion and stored energy

100
What is thermal energy?
heat is thermal energy it can be transferred from one place by one place to another
100
What is the energy transformation of a burning candle?
Chemical->Thermal->Chemical->Thermal
100

Which form of energy explains why solids have to be touched in order to get energy transfer in the form of heat.

conduction. The solids must be in physical contact. 

200

What precipitation falls to the ground frozen.

snow or hail.

200
What is an example of kinetic energy?
a car rolling down a hill
200

another name for wave energy

electromagnetic energy

200

What is the energy transformation in the Human body?

Chemical->Heat

Chemical -> mechanical

200

The type of energy transfer happens in waves or currents. It also only takes place in liquids and gas. 

convection.

300

Which factor does not affect the elastic energy of an object: Mass, Hardness, stretchiness, and compression?

mass

300

What happens to the molecules when energy is transferred?

the molecules collide. 

300
which law states that energy cannot be created or destroyed?
law of energy of conservation
300
What is the energy transformation in a flashlight?
Chemical->Electrical->Heat and Light
300

How are radiation, thermal energy, and electromagnetic related?

Radiation gives off thermal energy in the form of electromagnetic waves. 

400

What is the formula for Potential energy?

PE= MGH

Mass times Height times Gravity

400
What is mass?
Kinetic energy decreases as ........decreases?
400
What is why can energy only flow from hot to cold and not the other way around?
you can only take heat away
400
What is the energy transformation in a campfire?
Chemical->Heat and Light
400

What about the particles of a liquid and gas aid in convection?

because the particles in a liquid and solid are bouncing separately and widely, it is easier for the thermal energy to transfer in currents (the same motion as the particles).

Susan claims that the sailboat’s motion is based on kinetic energy being transferred to the sailboat and that the motion of the sailboat is impacted by the kinetic energy that is added or removed from the sailboat. Which three statements best support Susan’s claim?



A) People walking on the deck of the sailboat transfer energy to the sailboat and cause the boat to slow down.
B) Waves hit the side of the boat which transfers kinetic energy to the boat and causes it to slow down.
C) When the rain pours straight down on the boat, kinetic energy is transferred to the sailboat and the boat increases its speed.
D) Kinetic energy is transferred to the boat when the wind hits the sail and causes it to speed up.
E) Using the rudder (the underwater moveable fin) to turn the sailboat to the right causes it to lose kinetic energy as it slows down and turns.

What is how does a pendulum represent potential to kinetic energy?
Because when it is at its highest point then it is potential energy and when it rolls down to its lowest point it is kinetic energy.

What is how does energy flow when you have ice water and hot chocolate?
hot to cold

What is the energy transformation in a windmill?

mechanical -> electrical

500
What is one thing that shows conduction, convection and radiation?
A fire because when you put your hand over it you get convection, when you hang marshmallows over it you get conduction and when you put your hand beside it you get convection
