PIRA Classification: 1N21.40
Description: A cart is sent traveling down a track at a constant velocity. When it reaches an object hanging from an electromagnet, a switch is interrupted, causing the object to fall on to the cart. This cuts the velocity of the cart in half (as the object has the same mass as the cart).
Special Instructions: Turn on the magnet right before the demo and off right after.
Condition: OK
Setup time: 3 minutes
Safety Issues: None
