What does friction covert energy of motion into? thermal energy
What keeps a satellite in orbit around the earth? force of gravity
the greater the mass of an object..... the more inertia the object has

statement that describes events or relationships that exist in nature law
unbalanced force can keep an object moving in a circle circular motion
a force between surfaces that resists the movement of one surface past another surface friction

newton's laws of motion force = mass x acceleration a baseball hit with a bat flies farther than a bowling ball hit with a bat
newton's laws of motion for every equal and opposite action there is an equal and opposite reaction a balloon flies forward when air quickly escapes from it

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.
