|
Position-time graph |
The slope of the line determines the direction of the velocity of the object. |
|
|
Velocity-time graph |
Reveals useful information about the acceleration of an object. (-vel=-acc) (+vel=+acc)(no vel=no acc) |
|
|
Golden Equations |
a=(vf-vo)/t Vf=Vo+at d=Vot+1/2at^2 Vf^2=Vo^2+2ad |
|
|
