Unit of force

QuestionAnswer
Momentum the product of an objects mass and its velocity
FORMULA FOR MOMENTUM m=PV
LAW of conservation of momentum the totalmomentumof any group of objects remain the same unless outside forces also act on the objects.
Force A push or a pull that gives energy to an object
Units of force forces are measured 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 its motion
Balanced Forces the net force acting onan object is zero
Unbalanced Forces the net force acting on an object is not
Magnitude the amount of a measurement
Friction A force that one surface exerts on another when the two surfaces are in contact with each other
Static Friction friction between non-moving objects
Kinetic Friction friction between moving objects
Sliding Friction friction between objects that slide against each other
Rolling friction occurs when an object rools over a surface
Fluid Friction Occurs when an object moves through a fluid or a gas
Newtons frist law of motion Objects at rest wil stay at rest and objects in motion will stay in motion at a constant velocity unless acted on by an unbalanced force
Newtons second law of motion the net force acting on an object is equal to the product of the objects mass and acceleration
Newton's Third Law of Motion for every action force there is a reaction force that is equal, but acts in the
Law of Universal Gravitation all objects in the universe are attracted to each other; strength of attraction dependson the objects' masses and distance from each other
Freefall the motion of an object when GRAVITY is the only force acting on it
Termainal velocity greatest velocity of a falling object;occurs when the force of GRAVITY and EQUAL to the force of FRICTION
Weight a measure of force GRAVITY on an object
Mass the amount of matter in something
Centripetal Force the force of that is pulling an object in a circular motion
Geosynchronous Orbit occurs when an object orbits another object at a rate eual to the 2nd object's rate of rotation

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.
