conatant speed is speed that _________________ change does not
speed in a given direction velocity
rate of change in velocity acceleration
formula for finding acceleration final vel-intial vel ______________________ time
object traveling in a _________ motion is always changing motion circular
speed and _________ change in circular motion acceleration
push or pull and expressed in newtons force
combination of all forces net force
net force is 0 so it is a _____________force balanced
net force is not 0 so it is a_____________ force unbalanced
a force that opposes motion between 2 surfaces that are in contact friction
a froce between 2 moving surfaces kinetic friction
rolling friction is _________ than sliding friction less than
force applied to an object that is not kinetic to cause the object to move static friction
name one good thing that friction does stop a car from moving
name one bad thing that friction can do heat up the cars engine and wear down the parts
oil, wax, grease, water lubricants
make something smooth reduce friction
make something rough increase friction
force of attraction between objects due to their masses gravity
stated that gravity is a unbalanced force that can cause objects to move sir isaac newton
measured in newtons and depends on the force of gravity weight

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:
