Mini-Quiz: Using Vectors in Gravity Equations

1. What does the length of a vector arrow represent?

   The magnitude of the quantityCorrect. You understand vectors and gravity. The direction of the motionSorry, not correct. Try another button. It is only used for visualizationGood try, but not right. Select another answer.

2. When is the angle between a vector and the horizontal axis positive?

   The angle is always negativeSorry, not correct. Try another button. Whenever the Pythagorean Theorem holdsOops! Wrong answer. Re-read the question and try again. When the vector is positiveThat is Correct. You have a great future.

3. Why is distance a scalar quantity?

   Distance is not a scalar but a vectorOops! Wrong answer. Re-read the question and try again. Distance does not depend on direction of travelCorrect. You understand vectors and gravity. Because distance equals velocity times timeGood try, but not right. Select another answer.
