Graphing the Drop of a Ball from 2.0 Meters - An Introductory Free-Fall Acceleration Problem

The lesson begins with a review of a previous experiment involving the drop of a medicine ball. The teacher guides students through graphing acceleration, velocity, and position as functions of time. The acceleration is constant, resulting in a horizontal line on the graph. The velocity graph is a straight line with a negative slope, and the position graph shows a curve with an increasingly negative slope. The lesson concludes with a review of these concepts.

What is the initial velocity of the medicine ball in the Y direction when dropped from a height of 2.0 meters?

Explain the significance of the acceleration value of -9.81 meters per second squared in the context of free fall.

Describe how the velocity of the medicine ball changes over the time it takes to fall 2.0 meters.

How do you determine the final velocity of the medicine ball after it has fallen for 0.64 seconds?

What does the slope of the position versus time graph represent, and how does it relate to the motion of the ball?
