Motion ContinuedNotes in two column format
Acceleration • Rate at which velocity changes• Can be direction or speed• Can be faster or slower
23
Acceleration = Final speed – Initial speed / TimeEx: Final speed = 40 m/s
Initial speed = 0 m/sTime = 5 sec
A = (40 m/s – 0 m/s) / 5 sA = (40 m/s) / 5 sA = 8 m/s2
24*
A = Final speed – Initial speed / TimeEx: Final speed = 30 m/s
Initial speed = 10 m/sTime = 2 sec
A = (30 m/s – 10 m/s) / 2 sA = (20 m/s) / 2 sA = 10 m/s2
