Two Dimensional Motion: Projectiles

Lab Summary

Students use a photogate and mini launcher to measure the variables that affect the two-dimensional motion of a projectile launched horizontally, and then use those variables to accurately predict and test the projectile's horizontal range.

Theory

What is the range of a projectile launched horizontally? Develop a plan to measure the variables that affect the two-dimensional motion of a projectile launched horizontally, and then use those variables to accurately predict and test the projectile's horizontal range.

Method

Students assemble and mount a projectile launcher to their lab table and then make measurements of the variables (initial height and initial velocity) affecting the range of the projectile as it is launched horizontally. Students use their measurements to calculate a predicted value for the range of their projectile, and then they test their prediction. Students qualitatively analyze the accuracy and precision of their launcher based on the predicted range and the distribution of their actual range values.
