Projectile Motion



Pre-Lab Checklist

1. Describe in your own words the situation to be studied.

2. List and define each of the parameters to be measured directly.

3. List any quantities that will be calculated.

4. List any safety warnings given in the lab manual.


Equipment Notes

1. NEVER LAUNCH A BALL WHEN SOMEONE IS DOWN RANGE!!!!!

2. Put the carbon paper face-up under the piece of blank paper so that the landing ball does not tear up the carbon paper.

3. The launch position for the ball is the point where the ballleaves the launcher.

4. Make sure to clearly mark the launch position on the floor under thelauncher so that you can more easily and accurately measurexR.

5. Before calculating your predicted landing point for the angled launch,check the set-up on the launch ramp. Take any new measurements that you mightneed for your calculation.

6. Be careful of the units when performing your calculations.


Analysis Notes

1. Your results section should include values for the launch velocity ofyour ball and the predicted range for your angled launch. Be sure to identifywhich launcher you used and which angle.

2. Compare your range for the horizontal launch to the angled launch. For which launch did the ball travel further?

3. Were you able to correctly predict the range of the angled launch? Ifnot, critique your own prediction calculations to see if you can find yourmistake. Submit both your original calculations and your critique.

4. Is there a particular launch angle that would give the greatestrange for the ball? Explain, either with mathematics or with logic, how youknow which angle gives the maximum range.

5. How would the range change if we launced from the ground rather from thetable? Explain, either with mathematics or with logic, how you know whateffect the launch height has on the range of the projectile.
