QuestionAnswer
vector a type of variable that includes information that indicates direction as well as strength or size
vector diagram a type of graph in which the perpendicular axes represent the x- and y- directions the vector can have
magnitude the strength of the force in newtons (represented as "length" on the diagram)
scalar a type of variable such as mass or temperature that does not depend on direction and can be specified with a single value
resultant vector a single vector that represents the net sum of two or more individual vectors
component force the strength of the component
component a force along the x-, y-, or z- axis that represents another force
resolution of forces the process of breaking a force vector into its components
sine the ratio of the opposite side of a right triangle divided by the hypotenuse
cosine the ratio of the adjacent side of a right triangle divided by the hypotenuse
tangent the ratio of the opposite side of a right triangle divided by the adjacent side

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.
