  1. 1A tractor is moving in a straight line, in a direction we shall define as x. Its Position versus Time graph is shown by the graph at the left:
    1. AA
    2. BB
  2. 2A tractor is moving in a straight line, in a direction we shall define as x. Its Position versus Time graph is shown by the graph at the left:
    (a) What is the position of the tractor, in meters, at 2.0 seconds? [blank_start]Answer[blank_end]
    (b) What is the slope of the line in the graph above, in m/s? Give your answer in decimal form. [blank_start]Answer[blank_end]

    Bild zu Frage 2
    1. A0.8
    2. B0.3
  3. 3Suppose a second tractor is also moving in the x-direction, but at a higher speed. How would the Position versus Time graph of the second tractor be different to the one shown?Bild zu Frage 3
    1. AThe slope would be smaller.
    2. BThe slope would be greater.
    3. CThe intercept would be smaller.
    4. DThe intercept would be larger.
  4. 4Which of the following are vector quantities? Select two.
    1. AVelocity
    2. BSpeed
    3. CAcceleration
    4. DDistance
  5. 5If a car moves with constant acceleration, is it possible for the car’s velocity to change direction?
    1. AYes, this is possible if the car starts from rest, speeds up, slows to a stop, and then backs up.
    2. BYes, this is possible if the car is moving up and down a ramp, for example.
    3. CNo, this is not possible because the car is always speeding up.
    4. DNo, this is not possible because the car is either always speeding up or always slowing down.
  6. 6If a car’s initial velocity is zero and acceleration is negative, which of the following best describes the motion of the car?
    1. AThe car speeds up with a velocity in the negative direction.
    2. BThe car slows down.
    3. CThe car remains at rest.
    4. DThe car speeds up from rest.
  7. 7When acceleration and velocity vectors are pointing in opposite directions, the object is:
    1. Amoving at constant speed.
    2. Bnot moving.
    3. Cspeeding up.
    4. Dslowing down.
