km/hr. [0.0037 m/s, 0.013 km/h]
17. Describe the difference between distance and displacement. [distance is the path
taken without regard to direction, displacement is how far out of place you are from
your original position]
18. Describe the difference between speed and velocity. [speed is distance divided by
time, velocity is displacement divided by time]
19. Why is velocity a more helpful measurement of motion? [It utilizes direction which is
helpful for location, imagine trying to go to your friend’s place without a direction just a
distance!]
