Question

2 what is the difference between distance and displacement?
a none; distance and displacement are two words for the same concept.
b distance is the amount of space between two objs, displacement is the
difference in location between where an object started and ended its
motion.
c distance is the difference in location between where an object started
and ended its motion; displacement is the amount of space between two
objects.
d distance is needed in calculations of velocity; displacement is needed for
calculations of speed.

Explanation:

Distance refers to the total path length covered by an object (space between two objects). Displacement is a vector quantity that measures the change in position from the starting point to the ending point of an object's motion. Option B correctly differentiates them. Option A is wrong as they are different concepts. Option C has their definitions reversed. Option D is incorrect because speed uses distance and velocity uses displacement.

Answer:

B. Distance is the amount of space between two objects; displacement is the difference in location between where an object started and ended its motion.
