# Energy

### Mechanical Energy

Joule The unit of measurement of energy 1 Joule = 1N*m
Calorie The unit of measurement of chemically stored energy 1 calorie = 4.184J
Watt The unit of measurement of Power 1Watt,W = 1Joule/1second
Power Work done over a given time period. Equation- P=W/t P - power (Unit = Watts, W) W - work (in joules) t - time (in seconds)
Work Force applied for a distance *Work can give an object energy OR take energy away from an object. Equation - W=F*d W - Work (Measured in Joules) F - force (in Newtons) d - distance (in meters)
Energy An object's ability to do work *All energy is measured in Joules
Mechanical Energy The total amount of Potential and Kinetic energy that an object has. Mechanical Energy = GPE + KE
Gravitational Potential Energy An object's energy due to the distance, or height, between itself and a surface. GPE=mgh GPE= Gravitational Potential Energy m= mass (in kg) g= gravity (9.8m/s/s *No negative, energy is scalar) h= height/distance in Y-axis (in meters)
Chemical Potential Energy An object's energy due to chemical bonding. *Food, gas, oil are all examples.
Elastic Potential Energy Energy stored due to the stretching or compressing of a material such as a spring, rubber band, or other elastic material. Energy is created by the distance compressed or stretched.
Kinetic Energy An object's energy due to its velocity! KE=1/2mv^2 KE=Kinetic Energy m - mass (in kg) v - velocity (in m/s) Unit - Joules

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.
