Chap. 1 Kubalsky

QuestionAnswer
The starting point you choose to describe the position/location of an object. reference point
An object's distance and direction from a reference point. position
The process of changing position. motion
The difference between the initial (first) position and the final position of an object. displacement
A measure of the distance an object travels per unit of time. speed
The rate of change of position in which the same distance is traveled each second. constant speed
Speed at a specific INSTANT in time. instantaneous
The total distance traveled divided by the total time taken to travel that distance. average speed
The speed and direction of a moving object. velocity
A measure of the change in velocity during a period of time. Acceleration
TRUE or FALSE The distance an object moves is the actual length of its path. True
You can calculate units of speed by dividing the ____________ ________________by the ________it takes to go that distance. distance traveled (s=d/t) time
What can you use to show the relationship between speed and time and to determine information about the acceleration of an object? A speed-time graph
The __________of an object can be described by the object's position, velocity, and acceleration. motion
To calculate acceleration: subtract final ______ from initial ______. Subtract lesser ______from greater _______. ___________speed by time. speed time Divide
What are three ways an object can accelerate? Speeding up, slowing down, changing direction
What are ways velocity can change? When the speed of an object changes, when the direction of an object changes, or when both speed and direction change,
How can you describe the position of an object in two dimensions? Use two directions to describe it.
What's the difference between distance and displacement? Distance is the length of the path. Displacement is the difference between the first position and the final position.

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.
