A device is used to drop a ball and horizontally shoot a ball at the same time to see which will hit the ground first. Since both balls have the same vertical acceleration, they can be seen and heard hitting the floor at the same time.
* Equipment seen in the video may vary from equipment used in ND Demonstrations. See information and images below for ND equipment and setup.
Setup:
Use the ring stand to set up the ball drop/shot apparatus above the floor.
Push the tab back and into the slot to load the spring and prepare the apparatus to shoot the ball. Put the solid ball in front of the post and the channel ball onto the post behind the spring.
Flip the tab up out of the slot to release the spring and launch both balls.
Notes:
The balls will shoot some distance and roll. Please be observant of where they go and return them to the lab table.

Discussion and Polling Questions:
(before demo) Which ball will hit the ground first? Why?
(before or after demo) Do the masses of the balls matter?
Since air resistance is a thing we have to deal with, what about the two balls does matter?
Will the demo change if we shot one ball at an angle upward? What about downward?
Will the demo change if we shot the ball at a faster or slower speed?
Equipment Needed:
Ball Drop/Shot Apparatus
One Solid Ball
One Ball with a Channel Through It
Ring Stand
