The entire 7 story drop is viewed so that you can make measurements if desired.

The video tape shows a variety of objects being thrown off the roof of Van Allen Hall. Place a foam pad under the Photogate to prevent damage to the picket fence. needs to be carefully leveled to insure that the weight will fall at the proper distance from the wire so that good sparking is achieved.Inserting a switch between the power supply and magnet will make it easier to turn of the magnet and allow the weight to fall.Īnother way to quickly do a measurement of 'g' is to drop one of the picket fences through a Photogate. Measurement can also be made by using an inclined Air track and timing the cars through a known distance. The screws in the switch pad need to be tightened periodically to insure a good electrical contact. For ease of measurement the distance between the ball bearing when it is suspended in the electromagnet and the switch pad should be 1 meter. Hookup is as shown using the appropriate adapters.
