Determine the acceleration constant of gravity using free fall data. Introduce a formula used to determine instantaneous speed as the acceleration of gravity x time. Determine the instantaneous speed of an object at 5 and 6 seconds and then determine the average speed at these time segments. Find the average speed from the instantaneous speed/2.
Discuss the movement of an object when tossed upward. Describe the motion as it moves upward, its speed, acceleration and zero instant speed. Discuss the change in velocity.
