Physics: Energy

Work, Energies, mechanical energy, elastic potential energy, friction

Is energy (all types) conserved? YES
What is Work? amount of energy used applying a force for a certain distance.
What are the types of potential energy? PE due to gravity and elastic PE
In case of friction, what is the mechanical energy transformed into? Heat and/or sound.
What is elastic potential energy? Energy created by applying a force on a spring transferring energy into the spring.
What is potential energy due to gravity? It is the energy created from the position(height) of objected acted on by created by the attraction (force of gravity)
What is potential energy? Energy on an not moving object created by the location/position.
What is kinetic energy? Energy stored/gained by velocity and mass of the object in motion.
Does the reference point for height = 0 in an equation of PE and KE affect the result? No, because the KE friction won't be 0 anymore and would have a potential energy since the reference line is lower.
Is mechanical energy always conserved? NO

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.
