Energy Test

QuestionAnswer
the potential to do things energy
energy that exists due to motion is called this kinetic energy
energy cannot be created or destroyed only transferred from one form to another conservation of energy
this is demonstrated in collisions energy transfer
a push or a pull force
objects are not touching when transfer force on one another indirect force
this increases as it gets higher above the ground potential energy
when two objects touch each other and transfer energy, pushing the door open with your hand is an example of this direct force
when an object has more kinetic energy it has more of this speed
the total mechanical energy is the same before and after one of these collision
A marble at the top of a ramp is still. Because of this it possesses ___________________energy. potential
True or False: As an object speeds up , its kinetic energy increases. true
True or False: Total Mechanical Energy represents kinetic energy and light energy. false
if kinetic energy increases, potential energy decreases, and the total mechanical energy remains the same When a bike goes down a hill
Yes or no, When a motorcycle is moving at 10mph it has kinetic energy yes
Yes or no, When a bike is moving at 5mph it has no kinetic energy no
kinetic energy + potential energy =__________________ total mechanical energy
an object has a large amount of potential energy when it is_____________________? high off the ground
music coming from a speaker is an example of this. sound energy
Energy cannot be created or destroyed; it may be transformed from one form into another, but the total amount of energy never changes conservation of energy
an example of electrical energy being transferred into sound energy. Listening to the radio
a compressed spring has a lot or a little potential energy? a lot
Energy can be transferred through heat, light, and____________ sound

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.
