QuestionAnswer
Reference Point A place or object used for comparison to determine if something is in motion
Distance SI Unit Meter (measures the length of a path between two points)
Speed The distance an object moves per unit of time
Average Speed Calculate the total distance traveled by the total time. (Speed= Distance/Time)
Instantaneous Speed The speed at which an object is moving at a given instant in time
Velocity Speed in a given direction. If you know the speed and direction of an object, then you know the velocity
Graphing Motion Plotting time on the x-axis (horizontal axis), and distance on y-axis (vertical axis)
Slope is the steepness of the line, which shows how fast one variable changes in relation to the other variable. Slope= Rise/Run
Power The rate at which energy is transferred, or the amount of energy transferred in a unit of time. Power= Energy Transferred/Time
Kinetic Energy The energy an object has due to its motion
Potential Energy The energy an object has because of its position, also the internal stored energy of an object, such as energy stored in chemical bonds
Gravitational Potential Energy Potential energy related to an object’s height
Elastic Potential Energy The energy that can be associated with object’s that can be compressed or stretched
Mechanical Energy The form of energy associated with the motion, position, and shape of an object
Nuclear Energy The energy stored in the nucleus of an atom
Thermal Energy The total potential and kinetic energy of the particles in an object
Electrical Energy The energy of electrical charges
Electromagnetic Energy The form of energy that travels through space in waves
Chemical Energy The potential energy stored in chemical bonds
Energy Transformations a change in energy from one to another
Law of the Conversation of Energy Energy cannot be created or destroyed just changed from one form to another

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.
