Distance and Displacement

Distance

• The total length travelled

• How far an object is from its starting point in a straight line

• Location of an object relative to a defined zero point

Displacement

• The total length travelled

• How far an object is from its starting point in a straight line

• Location of an object relative to a defined zero point

Displacement is distance combined with

• direction
• speed
• velocity
• magnitude

What is a difference between distance and displacement

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

• Distance is always shorter than displacement

• Displacement can be equal to zero if the object finishes back where it started

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

If you draw a straight line on a map to see how far you are from where you started, you just found your ______.

• Distance

• Displacement

• Position

• Time

Which of the following describes distance and displacement correctly?

• The blue arrow shows distance and the orange arrows show displacement
• The blue arrow shows displacement and the orange arrows show distance
• Both arrows show distance only
• Both arrows show distance and displacement
