Question 1

What is the difference between distance and displacement?

Answer 1

Distance is the total length traveled and displacement is the distance between the starting and ending point.

Question 2

What is the difference between speed and instantaneous speed?

Answer 2

Speed is the rate at which an object travels and instantaneous is a certain speed for a certain distance.
