Motion (chpt 8-9)

Chapter terms

QuestionAnswer
Acceleration The rate at which an object changes its velocity
Air Resistance A friction-like force that opposes the motion of objects that move through the air
Average Acceleration Average rate at which an object changes its velocity
Average Velocity The rate of change in position for a time interval
Line of Best Fit A straight line that most closely fits the general shape outlined by the graph
Change in Velocity Change that occurs when the speed of an object changes, or its direction of motion changes, or both (Vf- Vi)
Deceleration The acceleration that is opposite to the direction of motion; a decrease in speed of an object
Displacement The straight-line distance and direction from one point to another
Distance (d) A scalar quantity that describes the length of a path between two points or locations
Gravity Attractive forces between two or masses; causes objects to be pulled towards the center of earth
Motion Diagram A diagram that gives a picture of motion by showing an object's position at given times
Position A vector quantity that describes a specific point relative to a reference point
Position-Time Graph A graph of an objects position during corresponding time intervals; (time = x-axis, position = y-axis)
Scalars Quantities that have only a magnitude (no direction)
Slope A direction of a line on a graph, either horizontal (zero), slanting up ( positive), or slanting down (negative) Formula= rise/run
Speed (v) A distance of an object travels given a certain time interval divided by the time interval
Time (t) When an event occurs
Time Interval The difference between the final time and the initial time
Uniform Motion Traveling in equal displacements in equal time intervals
Vectors Quantities that have both a magnitude and a direction
Velocity The displacement of an object during a time interval divided by the time interval
Velocity-Time Graph A graph of an object's velocity during corresponding time intervals (time= x-axis, velocity= y-axis)
Magnitude Refers to the size of a measurement or the amount (number) you are counting

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.
