# Unit 4 Flashcards

### Vectors and Forces

Vector A quantity that has both magnitude and direction
Scalar A quantity that has magnitude only
Magnitude the amount of a given measurement
Displacement a vector quantity which describes distance and direction
Component a single vector that may be added to one or more other vectors
Resultant the sum of any number of component vectors that are added together
Tip-to-tail a method of vector addition
Vector resolution a method of finding component vectors from a given resultant
Dynamics the branch of physics that describes how forces interact with matter
Equilibrium a state where the sum of the net forces acting on the object is zero
Inertia the force generated by an objectâ€™s weight
Weight the mass of an object times the acceleration due to gravity
Friction a force caused by electron repulsion
Air resistance a frictional force that acts against gravity as an object free falls
Static Friction a force that makes it difficult to move an object
Kinetic Friction a force that makes it difficult to keep an object moving
Net Force the difference between the applied force and friction
Normal Force a force that acts opposite gravity
Equilibrant a force that will place an object in equilibrium
Unbalanced Force an applied force that will take an object out of equilibrium

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:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

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.
