Question

1. Which is a vector quantity?
a
speed
b
velocity

2. What is the difference between distance and displacement?
a
Distance is measured in feet. Displacement is measured in meters
b
Distance is the difference between how quickly you move between two points. Displacement is the average of that motion.
c
Distance is a measure of length of travel. Displacement is the measure of the time it takes to move that length.

3. Choose all of the following that represent scalars.
a
position
b
time
c
acceleration
d
volume
e
velocity
f
mass

4. Which of the following is the scalar value?

a
Displacement
b
Distance

Answer 1

1. **Which is a vector quantity?**
**b. velocity**
(Velocity has both magnitude and direction, whereas speed only has magnitude.)

2. **What is the difference between distance and displacement?**
**c. Distance is a measure of length of travel. Displacement is the measure of the shortest straight line between the initial and final positions.**
(Note: The closest accurate choice regarding the general idea is implied in c, but the wording might not be perfect; displacement is the vector quantity representing the shortest path between two points.)

3. **Choose all of the following that represent scalars:**
**b. time**
**d. volume**
**f. mass**
(Scalars are quantities with only magnitude. Position, acceleration, and velocity have direction and are therefore vector quantities.)

4. **Which of the following is the scalar value?**
**b. Distance**
(Distance is a scalar quantity, while displacement is a vector quantity.)
