Distance Distance The length of a path between two points SI Unit = Meters (m) Large Distances = Kilometers (km) Small Distances = Centimeters (cm) m = 1 km 1 m = 100 cm Example: Rollercoaster Measure path car travels

Displacement Displacement The direction from the starting point AND the length of a straight line from the starting point to the ending point Used when giving directions (i.e. 15 blocks North) Example: Rollercoaster The direction from the starting point to the car And The length of the straight line from the starting point to the car NOTE: after you complete your ride and the car is back in place, the displacement is ZERO!!!

Distance/Displacement Demo

Vectors Vector A quantity that has magnitude and direction Magnitude = Size, length, or amount Represented by arrows on a graph or map Length of arrow = magnitude Displacement is an example of a vector

Combining Displacements Two displacements (represented by two vectors) SAME DIRECTION ADD MAGNITUDE Two displacements (represented by two vectors) OPPOSITE DIRECTION SUBTRACT MAGNITUDE
