1
Constant Velocity The position increases by 2 meters every second. The position decreases by 2 meters every second.

2
Example An object starts at a position of -5 meters and travels with a constant velocity of 3m/s for 5 seconds

3
Diagram – Motion Map Like the washers in the hallway. v v v v v v t = 2s x = 1m t = 3s x = 4m t = 4s x = 7m t = 5s x = 10m t = 0s x = -5m t = 1s x = -2m

5
t (s) x (m) 5432 0 1 -10 -5 5 10 t (s) v (m/s) 5432 0 1 -10 -5 5 10 Algebraic Graphical 3m/s Δx = 6m Δt = 2s Area = Δx

6
no direction Velocity – The rate at which the position changes. +/- sign gives direction Displacement – The change in position.

7
v = velocity (m/s) t = time (s) x = position (m) Δx = x 2 – x 1 (m)
