1H10.20 - Fan Cart & Sails

Code Number:
1H10.20
Demo Title:
Fan Cart & Sails
Condition:
Good
Principle:
Action & Reaction
Area of Study:
Mechanics
Equipment:
Fan Cart, Sail, and Aluminum Track.
Procedure:

Place the fan cart on a leveled aluminum track and turn on.  When released the cart should experience constant acceleration.

When doing action/reaction turn the fan on and show that the cart will move.  Place the sail on the cart and now the apparatus should stay in one place.

NOTE: On a completely frictionless surface the cart should move in the direction that the fan is blowing against the sail.
