Displacement

• In Physics, we define displacement as the change in an object's position

• We indicate displacement with the symbol

   $\Delta$  X  (Delta X)

• The SI unit of Displacement is Meters

Displacement

• Displacement is a vector quantity, this means it has both magnitude (number value) and direction

• Displacement can also be negative to show movement in a negative direction
