body falling in a vacuum
Velocity & Acceleration
A Behr free fall apparatus is seen in the
video. The bob is suspendedat the top of the apparatus by an
electromagnet. When the current in the magnet is cut off, the bob
falls to the ground. A spark timer triggering every sixtieth of a
second leaves atrail of spots on the paper tape behind the bob. In
this way, the distance vs. time data during the fall are
obtained.
