# Physics Ch. test

### Ch.3 test

Newton's third law every action force creates a reaction force that is equl in strength and opposite in direction
momentum equation p=mv
momentum the mass if an object multiplied by its speed or velocity
impulse equation Ft=mv2-mv1
impulse a change in momentum created by a force exerted over time
law of conservation of momentum the total momentum in a system of objects cannot change as long as all forces act only between the objects in a system
collision when two or more objects jit each other
elastic collision the objects bounce off each other with no loss in the total kinetic energy of the system
inelastic collision the objects change shape or stick together, and the total kinetic energy of the system decrases
the final velocity of two objects m1v1+m2v2=(m1+m2)v3

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.
