# Energy

### Potential and Kinetic energy

What is potential energy? the energy stored in an object because of its position
As a roller coaster begins to move, what happens to its energy? the energy an object has due to its motion
At what point on a roller coaster can you measure the highest potential energy? The potential energy is transformed into kinetic energy.
A ball rolls down a hill and then stops at the top of the next hill. Where is the kinetic energy the greatest? At the top of the largest hill because it has the most potential to cause change
Potential energy is in the process of increasing when something is going ...... At the very bottom of the hill
Kinetic energy _______________ as a ball rolls down a hill. Potential energy increases as the object is going uphill.
Potential energy ________________ as a ball rolls down a hill increases
What has an effect on potential energy? decreases
height and mass What has an effect on kinetic energy? height and mass
What is the Law of Conservation of Energy? mass and speed
Two forms of energy Energy is neither created nor destroyed.
Kinetic energy __________ as potential energy decreases. potential and kinetic
Kinetic energy ___________ as potential energy increases. increases
What causes a pendulum to stop moving? decreases
Energy due to motion is _________ energy. Air resistance creates friction that slows the pendulum down until it stops. This causes the gravitational energy to become potential energy. No energy is destroyed. (This is the Law of Conservation of Energy.)
______________ is the ability to cause change. energy
The faster an object moves, the ______ kinetic energy it has. more
___________ energy is stored energy. potential
What kind of energy is a stretched rubber band? potential

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.
