The difference between distance and displacement.
Displacement is the difference between initial and final position of an object, and speed is the measure of the distance an object travels per unit of time.
Speed is the difference between initial and final position of an object, and displacement is the measure of the distance an object travels per unit of time.
There is no difference.
Changing a reference point does not change the actual position of an object.
True
False

True
False
