Projectiles - 2-D Motion
Use a photogate to determine the initial velocity and then use this data plus initial height to predict the range of a projectile.
Projectiles are practical examples of two-dimensional motion. A common question found on AP Physics and other standardized exams is one involving the two-dimensional motion of an object launched horizontally. In this experiment, students predict the horizontal range of a ball launched horizontally from a measured height, a measured initial velocity, and a given value for the acceleration due to gravity.
- Use measured values for launch height and initial velocity to predict the horizontal range of a projectile.
- Establish a foundational understanding of the kinematic equations associated with the path of a projectile in two-dimensions.
Students gain experience conducting the following procedures:
- Launching the ball horizontally, so that it passes through two photogates as it leaves the barrel of the launcher.
- Measuring the launch height and initial velocity of the steel ball.
- Predicting a horizontal range using the measured data.
- Relaunching the ball and allowing it to strike the floor.
- Comparing the predicted and experimental ranges.
