Answer
-
A
-
B
Question 2
Question
A 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]
Answer
-
0.8
-
0.3
Question 3
Question
Suppose 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?
Answer
-
The slope would be smaller.
-
The slope would be greater.
-
The intercept would be smaller.
-
The intercept would be larger.
Question 4
Question
Which of the following are vector quantities? Select two.
Answer
-
Velocity
-
Speed
-
Acceleration
-
Distance
Question 5
Question
If a car moves with constant acceleration, is it possible for the car’s velocity to change direction?
Answer
-
Yes, this is possible if the car starts from rest, speeds up, slows to a stop, and then backs up.
-
Yes, this is possible if the car is moving up and down a ramp, for example.
-
No, this is not possible because the car is always speeding up.
-
No, this is not possible because the car is either always speeding up or always slowing down.
Question 6
Question
If a car’s initial velocity is zero and acceleration is negative, which of the following best describes the motion of the car?
Answer
-
The car speeds up with a velocity in the negative direction.
-
The car slows down.
-
The car remains at rest.
-
The car speeds up from rest.
Question 7
Question
When acceleration and velocity vectors are pointing in opposite directions, the object is:
Answer
-
moving at constant speed.
-
not moving.
-
speeding up.
-
slowing down.
