The motion of an object can be described by measurements of its position at different times. Velocity is a measure of the rate of change of position of an object. Acceleration is a measure of the rate of change of velocity of an object. This change in velocity may be a change in speed and/or direction.

2.2 Acceleration A. Describe motion in terms of changing velocity B. Draw and interpret velocity versus time graphs C. Use equations of motion to calculate displacement, time, or velocity under acceleration 2.3 Falling Objects A. Calculate displacement, velocity, and time at various points in free-fall motion California Standards Covered 1.
