1H10.20- Fan Cart & Sails
![]() |
![]() |
Code Number: 1H10.20
Demo Title: Fan Cart and Sails
Condition: Good
Principle: Action & Reaction
Area of Study: Mechanics
Equipment:
Fan Cart, Sail, and Pasco Aluminum Track.
Procedure:
NOTE: The fan is also used for the 1C20.75 demo. See: the 1C10.10 and 1J30.60 entries also.
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.
