Mrs. Patelunas' Forces, Friction and Momentum Vocabulary

kinetic friction the friction caused by moving objects
static friction the friction that exists between two stationary objects
force a push or a pull that gives energy to an object
momentum the product of an object's mass and its velocity
Newtons the unit of force
Net Force the total of all the forces acting on an object
Law of Conservation of Momentum the total momentum of a group of objects remains the same after collision unless forces like gravity or friction act on the objects.
balanced forces the net force acting on an object is zero
unbalanced forces the net force acting on an object is not zero
sliding friction the type of kinetic friction that occurs when two solid objects rub against each other
fluid friction the type of kinetic friction that occurs when objects move through a liquid or a gas
rolling friction the type of kinetic friction that occurs when an object rolls over a surface

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:
