17. Draw a force diagram for each ball as it flies through the air.
18. Based on these force diagrams, describe the motion of the balls in
the x direction.
19. Based on these force diagrams, describe the motion of the balls in
the y direction.
20. How does the time of free fall compare for the two balls? Explain.
Changing Launch Velocity
1. Repeat the above experiment, depressing the plunger of the launcher
to the "second click" instead of the "first click."
2. Draw a force diagram for each ball as it flies through the air.
3. Ask students to predict the horizontal range and time of free fall
for this new launch setting.
4. How does the horizontal range compare to the "first click" setting?
Explain.
5. How does the time of free fall compare to the "first click" setting?
Explain.
6. What must be changed to affect the time of free fall?
7. If desired, repeat the experiment for the "third click."
Changing Mass
1. Repeat the above experiment, but hang the hollow steel ball instead
of the solid steel ball. Use the solid steel ball in the launcher.
2. Draw a force diagram for each ball as it flies through the air.
3. Ask students to predict the horizontal range and time of free fall
for this combination of balls.
4. How does the horizontal range for balls of unequal mass compare
to using balls of equal mass? Explain.
5. How does the time of freefall for balls of unequal mass compare to
using balls of equal mass? Explain.
6. What must be changed to affect the time of free fall?
Note: It is not recommended
to use the most powerful
launch setting on the Long
Range Launcher (ME-
6801) for this experiment.
