Physics Projectile Project: Part II (student handout continued)
Objective:
Your team will use the ratio of baking soda to vinegar that provided the lowest height in Part I to find the launch angle that
produces the greatest range.
Notes:
• All testing will be done in the gym or outside.
• The projectiles range will be measured from the front of the film canister to the exact point the projectile hit the ground.
• The projectiles initial velocity will be calculated from Part I using time and this formula: v
f
= v
i
+ at
• The projectiles theoretical range will be calculated using the range equation: R = v
f
2sin(2θ)/g.
Requirements:
• Your group will record data tables showing the range of projectile and angle of launch.
• A sample calculation for initial velocity and theoretical range.
• An explanation, using the data as evidence, of how your group made a claim stating which launch angle will produce
the greatest range.
• Perform a percent error analysis using experimental vs. theoretical range calculations:
• Groups will submit a google document with the required data and conclusions.
