Describing Motion

Vocabulary

QuestionAnswerFormula
The process of changing position. Motion *An object is in motion if the distance between the object and a reference point is changing
A distance from starting point to final point. Displacement Distance= x + y
A length of the path taken. Distance Displacement= C^2=A^2+ B^2
A measure of the distance an object travels per unit of time. Speed Speed= distance/time Distance= Speed * Time Time= Distance/Speed
The speed and direction of a moving object. Velocity Velocity= distance/time Distance= Velocity * Time Time= Distance/Velocity
The rate of change of position in which the same distance is traveled each second. Constant speed
An object's speed at a specific instant in time. Instantaneous speed
The total distance traveled divided by the total time taken to travel that distance. Average speed Average speed= total distance/total time
A measure of the change in velocity during a period of time. Acceleration Acceleration= final speed - initial speed/total speed a=v2 - v1/t
The starting point you use to describe the motion or the position of an object. Reference point
An object's distance and direction from a reference point. 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.
