Just a thought . . . What does it mean for velocity to be the derivative (a.k.a. slope) of position? Specifically what does it mean about the direction of the velocity?
Position x y Instantaneous Velocity The direction of instantaneous velocity is ALWAYS tangent to the path being traversed! Not t

What does UNIFORM circular motion mean? Velocity Position x y Uniform means that the magnitude of velocity does not change. Only the direction changes.
What acceleration is required to make this happen? Think about our experiment on Ingram . . . Velocity Position x y Remember we said that if a projectile is launched straight up, the acceleration due to gravity only changes the magnitude of velocity since it acts in either exactly the same or opposite direction as velocity. Acceleration
