conservation of Energy

energy is the ability to do work
kinetic energy energy that an object has due to its motion
kinetic energy calculated by taking 1/2 of the product of the mass times the square of the velocity
potential energy energy that an object has due to its shape or position
graviatational potential energy energy an object has due to its height above the earth's surface and its weight
law of conservation of energy states that energy can neither be created nor destroyed by ordinary means
mechanical energy the energy associated with motion (kinetic energy)
heat energy the internal energy of a body (the total kinetic and potential energy of the particles in the body)
chemical energy the energy a substance has due to the chemical bonds found within its molecules
electromagnetic energy energy associated with a moving electric charge
nuclear energy the energy contained within the nucleus of an atom (most concentrated form of energy)
the more massive body consider two moving objects. each is moving at the same velocity. one is more massive than the other. which one has the greate kinetic energy
the body with the higher speed consider two bodies of the same mass. one is moving faster than the other. which one has the greater kinetic energy
kinetic energy to potential energy one of the most common energy conversions involges te changing of what?

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.
