______ are the very bottoms of a transverse wave. Troughs
______ the starting point of the wave. Restingpoint
In a ________, the particles move perpendicularly compared to the wave. Transverse Wave
A ________ has the particles move back and forth, just like the wave. Longitudinal Wave
_______ are the part of a longitudinal wave that are closer together. Compressions
_______ are where the particles are more spread out in a longitudinal wave. Rarefactions
______ is an activity involving a force and movement in the direction of the force. Work
_____ is the rate of doing work or the rate of using energy. Power

A 60 N girl pushed a cart 10 meters, what is the amount of work? 600 Joules
If you do 25 Joules of work in 5 seconds, how much power did you generate? 5 Watts
The speed of the wave was 5 cm/s and the wave traveled 45 cm. How long did it take for the wave to travel? 9 Seconds
A boy did 400 Joules of work and generated 80 Watts, how long did it take him? 5 Seconds
A waves travels for 4 Seconds and the speed was 40 cm/s, how far did the wave travel? 160 Centimeters
If you carry a box for 12 meters and generated 144 Joules, how many newtons did the force have? 12 Newtons
A boy generated 250 Joules of work, so how much energy did he expend? 250 Joules of Energy

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.
