Momentum

QuestionAnswer
Newton's 1st Law an object in motion stays in motion
Momentum Definition mass in motion
Momentum Equation p=mv OR momentum=(mass)(velocity)
Momentum Does Not Equal... intertia
Units Of Momentum kg x m/s^2
A Car Will Take Longer To Stop If It Has A... crumple zone
Impulse Definition change in momentum (∆p)
Impulse Equation With Mass & Velocity J=m∆v
Impulse Equation With Force & Time J=(F)(t)
In Tennis, The Impulse On The Ball Equals... The Impulse On The Racket
Direction In Momentum direction matters because momentum is based on velocity, which is a vector
Systems In Science an object or group of objects that scientists are interested in analyzing
System Objects objects in the system are in the system, and objects outside the system are out of the system
Isolated/Closed Systems only objects in the system interact with one another
Momentum System Equation Psys=P1+P2+... OR Psys=m1v1+m2v2+...
Momentum Can Be... transferred
The Initial Momentum Should Equal The... Final Momentum
Bar Charts chart that tracks how things change, especially within systems
Heavier Items Need... less speed than lighter items to meet the same momentum
Elastic Collision when two objects collide and bounce off each other and momentum is constant
Inelastic Collision when two objects collide and stick together. Objects have the same velocity after the collision
Explosion Collision when two objects start together, and then blow apart
Collision Equation m1v1+m2v2=m1v1'+m2v2'

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.
