TermDefinition
Energy Transfer The movement of the same energy from one place or object to another.
Energy Transformation The change of energy from one form to another form.
Total Energy (TE) potential energy + kinetic energy+ heat
Matter Anything that has a mass and takes up space
Mass How much matter is in an object.
force a push or pull upon an object resulting from the object's interaction with another object; has magnitude and direction
Kinetic Energy The energy an object has due to its motion
Velocity The speed and direction of a moving object
Gravitational Potential Energy Potential energy that depends on the height of an object
Thermal Energy Heat energy caused by the motion of the particles of a substance
What happens to some of the energy during a transfer It can be transformed into heat
Law of conservation of energy Energy cannot be created or destroyed
How does friction affect the pendulum? Gradually changes the energy to heat and pendulum eventually stops
Energy The ability to do work; the property of an object that allows it to do work
Potential Energy type of stored energy that an object or system of objects may have based on their size, shape, position, or even material they are made from
friction A force that opposes motion and releases heat
When molecules are heated Molecules have more KE, vibrate more, begin to spread apart
When an an object has more mass the object will have more KE
When an object increases it's height it's PE will increase as well.
Colder tempatures result in atoms compressing together
High Temperature Unstable, High KE
Low Temperature Unstable, High PE
Room Temperature Balanced State, Stable (most things are at this state)
Transfer Examples PE to PE, KE to KE
Transformation Examples PE to KE, KE to Heat
Factors that INCREASE KINETIC ENERGY temperature and mass

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
