10 cards from this deck
Distance travelled divided by time taken
vav=DΔtv_{av} = \frac{D}{\Delta t}vav=ΔtD
Scalar (magnitude only, no direction)
Always positive
Change in position divided by time taken
vˉav=ΔxˉΔt\bar{v}_{av} = \frac{\Delta \bar{x}}{\Delta t}vˉav=ΔtΔxˉ
Vector (has magnitude and direction)
Can be positive or negative
Zero (displacement is zero)
Speed depends on path; velocity doesn't
