Introduction
It is likely that you have learned to describe linear and parabolic motion using equations that involve x and y directions. When objects move in circles, it can be convenient to use a different coordinate system. Whether an extended object is rotating or a point particle is moving in a circle, we can describe the circular aspect of the motion with equations similar to those used for linear motion, but employing polar coordinates.
Objectives
In this experiment, you will
- Use video analysis techniques to obtain angular position, angular velocity, and time data for a video of a turntable spinning.
- Examine graphs and equations of the motion for rotational motion.
