Question

when would distance and displacement be equal?
swinging back and forth
driving forward on a straight road
rolling down a curved ramp
bouncing up and down

Explanation:

Distance is the total path length traveled, while displacement is the straight - line distance from the starting point to the ending point. When an object moves in a straight line in one direction, the total path length (distance) and the straight - line distance (displacement) are the same. In the other options, the object's motion has changes in direction which make distance greater than displacement.

Answer:

B. driving forward on a straight road
