  1. -Distance is the total amount travel.
    -Displacement-is the shortest distance between two objects.
    -V=d/t
    -Average velocity can be found in( V+Vo)/2 initial.
    -Acceleration -is any change in speed/velocity.
    -A car is moving at 10m/s and 4 seconds later it is moving 30m/s. What is its average acceleration in this 4 second time period?
    -Identify concepts- acceleration (a) time (t)
    -Identify units- 10m/s=Vo
    4s=t
    30m/s=V
    -A car travelled 100 meters in 5 seconds. Its final velocity was measured to be 25 m/s. What was its initial velocity in the 5 second time interval?
    -Find equation with- a=30m/s-10m/s/45=20m/s/45=5m/s2=a
    -Id concepts
    Velocity Final=Vf Velocity intel=Vo Time=t
    -Units
    100m=d 5s=t 25m/s=Vf
