Impulse & Momentum

Vocabulary

TermDefinition
Momentum vector that is a moving mass; how difficult it is to stop something
Conservation of Momentum law that states the total momentum of two objects is the same before vs. after a collision
Impulse change in momentum, caused by a force acting over a certain amount of time
Elastic collision where objects bounce off each other; kinetic energy is conserved
Inelastic collision where objects stick together, total kinetic energy decreases
Explosion "collision" where objects are stuck together and then separate, total kinetic energy increases
Energy Transformation energy is neither created nor destroyed, but transformed into other types
Conservation of Kinetic Energy when the total amount of KE is the same before vs. after a collision
Impulse-Momentum Theorem amount of momentum gained in a collision must be the same amount lost by another object (equal & opposite impulses)
Newton's 3rd Law forces between two interacting objects are equal and opposite of each other
Internal forces that are found within a specific system of interacting objects
External forces that are outside of a specific system of interacting objects
Thermal type of energy that is "produced" from friction
Magnitude size or quantity (number)
Vector variable that has both magnitude and direction

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.
