1.2.B—Describe the average velocity and acceleration of an object

Describe the average velocity and acceleration of an object.

• Averages of velocity and acceleration are calculated considering the initial and final states of an object over an interval of time.
• Average velocity is the displacement of an object divided by the interval of time in which that displacement occurs.
• Average acceleration is the change in velocity divided by the interval of time in which that change in velocity occurs.
• An object is accelerating if either the magnitude and/or direction of the object’s velocity are changing. TOPIC 1.2 Displacement, Velocity, and Acceleration
• Calculating average velocity or average acceleration over a very small time interval yields a value that is very close to the instantaneous velocity or instantaneous acceleration.
