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.
