Experiment

Experiment DL02    Free Fall Acceleration

Objectives
  • Measure the acceleration due to gravity using a motion sensor
  • Demonstrate that the acceleration due to gravity is independent of the mass of an object
  • Study the s-t and v-t graphs for a bouncing ball
Description
In this activity, you will use a Motion Sensor to monitor the position of a falling object. Both the s-t and v-t graphs would be plotted by the computer. The acceleration due to gravity is obtained from the slope of the v-t graph.

In Experiment 1, you will record the position of a falling book.

In Experiment 2, you will record the position of a bouncing ball.
