Velocity =

Δx/t

displacement Δx / time

UNIT: m/s

20

Instantaneous Velocity =

assess the SLOPE of the graph @ that point in time.
the tangential line of the slope
rise/run

21

Acceleration =

Δv/Δt

V(final) - V(initial) / Δtime

UNIT: m/s^2

22

Kinematic Formula 1. (missing Δx)

V = Vi + a.t

23

Kinematic Formula 2. (missing a)

Δx = (Vf + Vi)/2.t

24

Kinematic Formula 3. (missing Vf)

Δx = Vi.t + 1/2.a.t^2

25

Kinematic Formula 4. (missing t)

Vf^2 = Vi^2 +2.a.Δx
