The Forces

No Description

QuestionAnswer
Momentum What you get when you multiply an object's mass and it's velocity.
The Formula for Momentum m=pv
Law of Conservation of Momentum An objects momentum stays the same unless a different force acts on the object.
Force A push or a pull that causes an object to move.
Unit of Force Newton
Net Force All the forces acting on an object.
Inertia The tendency of matter to not want to change it's motion.
Unbalanced forces When the Net force trying to get the object to move is not zero.
Balanced forces When the Net Force trying to get an object to move is zero.
Magnitude The size of a measurement
Friction A force that occurs when two objects rub against each other.
Static Friction Friction between two objects that don't move.
Kinetic Friction Friction between two objects that are moving.
Sliding Friction Friction that is caused by two objects rubbing against each other.
Rolling Friction Friction that happens when an object is rolling.
Fluid Friction Friction that occurs when an object moves through a liquid.
Newton's First Law of Motion An object won't move unless a force acts apon it.
Newton's Second Law The Net Force working on an object is equal to what you get when you multiply the object's acceleration and mass.
Newton's Third Law Every action as an opposite and equal reaction
Law of Universal Gravitation Everything is affected by gravity, the strength of that gravity depends on the mass and relative distance of objects to each other.
Freefall When gravity is the only force acting on an object.
Terminal Velocity When the force exerted on and object by friction and gravilty are equal.
Weight How strong the gravity acting on an object is.
Mass How much matter is in something.
Centripetal Force The force that acts circularly toward the center point of the circle.
Geosynchronous Orbit This happens when one object orbits another object at the same rate at he other object spins.

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.
