Make, label, and title the data table in your lab book unless one has been provided.

Select any of the 8 objects from the objects box by clicking on it. The object's mass will appear in the computer data table.

Choose a value from the energy box, 1 µJ, 1 mJ, or 1 J. (1 Joule = 10⁶ µJ)

Use Newton's formula (E = ½mv²)to calculate the speed from the mass and energy last entered into the table. Enter this value into the box on the table. Hit the Enter key.

The computer then calculates the speed from Newton's formula so you can check your result.

The object you selected falls into the machine next to Coty and is shot out with the chosen energy. The object's speed is measured by Coty's radar gun and recorded in the last column of the table.

Run the experiment at least 8 times, recording the data in your notebook after each run.
