# momentum and impulse

### quiz 11/18/16

conservation of momentum the total momentum remains constant unless a net external force acts on a system
momentum product of the measure and velocity of an object
what is momentum measured in? expressed in "newton seconds" (Ns)
impulse the quantity of force and time applied in a situation
spring compressible, helical structure that returns to its uncompressed state upon release
momentum is also a measure of what? an object's resistence to outside forces
forces move- or else they wouldn't be forces
for KE= .5mv^2, doubling the velocity will have the same impact as quadrupling the mass
mass and velocity in KE=.5mv^2 are inversely proportional
for any 2 objects colliding, the net kinetic energy before... will equal the net KE after impact
momentum increases... when either mass or velocity increases
force is... expressed in newtons N=kg(m)/s^2
momentum formula p=mv

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.
