100
Lowering an object decreases its potential energy.
What is true?
100
this defines kinetic energy.
What is energy of motion?
100
Is the ability to cause change.
What is energy
100
this is the measure of the average kinetic energy of the particles in an object.
What is temperature?
100
If an object has energy, this means that the object has the ability to cause this.
What is change?
200
the energy an object has due to its position.
What is gravitational potential energy or GPE?
200
a rock sitting on the ground has this much kinetic energy.
What is zero?
200
Unit that energy is measured in.
What is a joule?
200
this material REDUCES the flow of heat by conduction, convection and radiation.
What is an insulator?
200
You can determine how much energy foods can give you by checking this.
What is calorie content?
300
food and fuel are this kind of energy.
What is stored chemical potential?
300
this happens to kinetic energy as mass increases.
What is increases?
300
energy doesn't have to involve motion.
What is true?
300

What is air?
300
According to the law of conservation of energy, the total amount of energy in the universe is this.
What is constant or unchanging.
400
formula for GPE
What is GPE=mgh
400
formula for kinetic energy
What is KE=1/2 mv^2
400
the sum of all kinetic and potential energy in a system.
What is mechanical energy?
400
A fire burns you by transferring this energy.
What is thermal?
400
These do not allow heat to move easily through them.
What is insulators?
500
object has a mass of 7kg and is 4m above the ground this is the GPE of the object.
What is 274J?
500
an objects mass is 60kg moving at a speed of 3m/s this is the objects kinetic energy?
What is 270 J?
500
this energy travels from the sun to the earth and is transformed into light energy by plants.
What is radiant energy?
500
Convection occurs through this phase of matter.
What is a liquid?
500
