Momentum the product of an object's mass and its velocity
Formula for Monentum m=pv
Law of Consevation of Momentum the totl momentum of any group of objects remains the same unlss outside forces also act on the objects
Force a push or a pull that gives energy to an obct
Units of Force fources are measurd in Newtons; N
Net Force the total of all the forces acting on an object
Inertia the tendency of matter to resist a change in ts motion
Balanced Force(s) the net force acting on an object is zero
Unbalanced Force(s) te net force acting on an object is not zero
Magnitude the amount (size)of a measurement
Friction a force that one surface exerts on another when the two surfaces are in contact with each otr
Static Fricon friction between non-moving objects
Kinetic Friction friction between moving objects
Sliding Friction friction between objects that slide (rub) against each other
Rolling Friction occurs when an object rolls over a surface
Fluid Friction occurs when an object moves though a fluid or a gas
Newton's First Law of Motion objects at rest will stay at rest and objects in motion will stay in motion at a constant velocity unless acted on by an unbalanced force
Newton's Second Law of Motion the net force acting on an object is equal to the product of the object's mass and acceleration
Newton's Third Law of Motion for ecery action force there is a reaction force that is equal, but acts in the oppisite direction
Kaw of Universal Gravitation all objects in the universe are attracted to each other; strength of attraction depends on the objects' masses and distance from each other
Freefall the motion of an object when GRAVITY is the only force acting on it
Terminal Velocity greatest velocity of a falling object; occurs when the force of GRAVITY is EQUAL to the force of FRICTION
Weight a measure of the force of GRAVITY on an object
Mass the amount of matter in something
Centripetal Force the force that is pulling an object in circular motion towards the center of the circle
Geosynchronous Orbit occurs when an object orbits another object at a rate equal to the 2nd object's rate of rotaion

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.
