10 cards from this deck
Coordinate system with fixed origin to measure positions
Average position of all matter in an object
Scalar - total path length with no direction
Vector - change in position with direction, symbol s⃗\vec{s}s
v=stv = \frac{s}{t}v=ts where sss is distance, ttt is time
Vector - rate of change of displacement, v⃗=Δs⃗Δt\vec{v} = \frac{\Delta\vec{s}}{\Delta t}v=ΔtΔs
Speed
Distance travelled
vavg=ΔdΔtv_{\text{avg}} = \frac{\Delta d}{\Delta t}vavg=ΔtΔd
v⃗o−v⃗d\vec{v}_o - \vec{v}_dvo−vd (observer minus distant object velocity)
