Data Sheet: Activity 2 - Conservation of Energy

Table I - Ball Mass

Complete the table below using data found under the Activity-Form tab.

Ball 1 Mass (kg)	Ball 2 Mass (kg)
0.200	0.250

Table II - Launch Without Ramp

Complete the table below using data from Table I, data from your Energy Plots (see the Energy Plots tab), and information found under the Background tab.

Note: Be very careful with units to get correct answers! 1.00 cm = 0.0100 m, 100 mJ = 0.100 J.

Launch Without Ramp

Spring 1

1. select Spring 1 by clicking or tapping on its button
2. select Ball 1 by clicking or tapping on its button
3. set spring compression to its maximum value by moving the slider completely to the left, record the value (in meters) in Table II of your Activity Form
4. click the Launch button
5. visit the Energy Plots tab and see the following plots: Potential Energy Plot ? record Spring potential energy (in joules) in Table II Kinetic Energy Plot ? record Max Kinetic energy (in joules) in Table II Combined Energy Plot ? view PE (blue), KE (red), and total energy E (pale yellow) Note: your instructor may require these plots to be submitted with your Activity Form
6. press the reset button
7. for Trial 2 repeat steps 1-6 using a different value of spring compression in step 3
