This lab will let you examine the relationship between distance an object falls and its speed after falling said distance.

The lines on the PVC pipe are 5 cm apart. The cylinder is 5 cm tall.

Set your nail location and the click on the mass to drop it onto the nail.

Click on the head of the nail to pull it out of the PVC and allow the mass to fall through the photogate.

Use the difference in time between blocked and unblocked to get the approximate speed of the mass as its center is passing the eye of the photogate.

When you are ready to start the experiment, click on the begin button
