Introduction
Up to this point it is likely that you have examined the motion of an object in one dimension only—either falling vertically under the influence of Earth’s gravity or on a horizontal or inclined surface.
In this experiment, you will examine the behavior of a projectile—an object moving in space due to some initial launching force. Such an object can undergo motion in two dimensions simultaneously. Using the Vernier Video Analysis app, you will compare features of the position vs. time and velocity vs. time graphs with those of one-dimensional motion.
Objectives
In this experiment, you will
- Use video analysis techniques to obtain position, velocity, and time data for a projectile.
- Analyze the position vs. time and velocity vs. time graphs for both the horizontal and vertical components of the projectile’s motion.
- Create and analyze your own video of an object undergoing projectile motion.
