Potential energy

QuestionAnswer
Energy associated with the position of an object POTENTIAL
Objects close to the surface of the Earth interact with the Earth through this force. GRAVITATIONAL
What happens to an object’s gravitational potential energy as it falls to the earth? As it moves toward the earth, the gravitational potential energy is converted into kinetic energy.
Two skiers, Dan (80.0 kg) and Anne (50.0 kg, are at the top of a break-a-leg ski trail with a vertical height of 300 meters. Which one will produce the most kinetic energy as they ski down the hill? Why? Their potential energy is converted to kinetic energy as they go down the hill. Since kinetic energy involves mass, Dan, with the greater mass will produce the most kinetic energy. Other parts of the equation would be the same for both.
If you lifted a book vertically from the table what kind of energy are you giving it? Gravitational potential energy...the ability to fall.
As you wind the key on a toy, what kind of energy are you putting into the toy? Potential energy
What kind of energy does a car battery have? Chemical potential energy

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.
