1. Which is a vector quantity?

Question

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.)
