Speed, distance, and displacement

What is a difference between distance and displacement

• Distance is measured in seconds and displacement is measured in meters

• Distance is always shorter than displacement

• Displacement can be equal to zero if the object ends in the place it began in

• Distance can be equal to infinite when only a small distance has been travelled
