Questions

Question 1 .

True or False: The sum of two vectors is another vector.

Answer 1

Question 2

True or False: The length of a 2D vector is equal to the square root of the length of the hypotenuse of a right triangle formed by the lengths of thehorizontal and vertical components of the vector.

Answer 2

Question 3

True or False: The sum of a vector and a point is another vector.

Answer 3

Question 4

True or False: A vector has only two properties: length and direction. It does not have a position property.

Answer 4

Question 5

True or False: When you draw a vector, you must draw it in a specific location.

Answer 5

Question 6

True or False: When you draw a vector, you can draw it anywhere in space, and one position is equally as valid as any other position.

Answer 6

Question 7

True or False: It's legal to draw a vector anywhere in space. Therefore, drawing the vector in one position doesn't have any advantage over drawingit in another position.

Answer 7

Question 8

True or False: If you add two or more vectors to produce a sum vector, and then draw the vectors that were included in the sum with the tail of onevector coinciding with the head of the previous vector, the head of the last vector that you draw will be positioned at some particular point in space.

If you then draw the vector that represents the sum vector with its tail coinciding with the tail of the first vector that you drew, its head willcoincide with the head of the last vector that you drew.

Answer 8

Question 9

True or False: In order for the head-to-tail rule to apply, the coinciding tails must be drawn at the origin.

Answer 9

Question 10

True or False: The validity of the head-to-tail rule is limited to the sum of two vectors in two dimensions.

Answer 10

Question 11

True or False: A point has a location property. In fact that is the only property that a point does have. Because a point is simply a location inspace, that location is always specified relative to some coordinate frame.

Answer 11

Question 12

True or False: The location of a point in world coordinates is independent of the values of the coordinates of the point with respect to changes in thecoordinate frame.

Answer 12

Question 13

True or False: If an object is registered as an ActionListener on a button, the doAction method belonging to the object is called each time the user clicks the button.

Answer 13

Question 14

True or False: The result of adding vectors depends on the order in which you add the vectors.

Answer 14

Question 15

True or False: The length of the sum of two vectors is not necessarily equal to the sum of the lengths of the two vectors.
