How can we describe the motion of objects launched into the air? Use this video of a ball launched into the air after rolling on a level table to find out.
These videos were created to be used in an introductory physics class to introduce two-dimensional "projectile motion".
Directions:
1. Pause the video at different times to collect the launched ball's horizontal position and vertical position both ON and OFF the table. This data can be used to graph the horizontal and vertical positions as they change over time to learn about the ball's motion.
2. Make a horizontal position versus time graph to analyze the horizontal part of the ball's motion.
3. Make a vertical position versus time graph to analyze the vertical part of the ball's motion.
4. Consider the forces acting on the ball both ON and OFF the table.
To see how the ball moves differently when launched at different speeds, see the linked videos below.

"Projectile Investigation #2 (Medium Speed)": youtu.be/YiEOW9Ew5BU
"Projectile Investigation #3 (Fast Speed)": youtu.be/pJj9IUadjJs
Also, see the linked video below to see how the vertical part of the ball's motion compares with how a dropped object behaves.
