Resolution of Forces: Statics of Rigid Bodies
Balloon & Fan
PIRA Class: 1J30.05*

Purpose
To observe an object suspended in air due to the zero net force on the

Description
Observe balanced forces by suspending a balloon in mid air using a mini fan.
1. Use a medium sized balloon
2. With fan on & pointed upward, release balloon gently ~6" over the fan.
3. Keep fan steady & balloon's motions over the fan should steady out too.
VARIATIONS:
- Terminal Velocity: Drop balloon from a relatively high point and observe its constant motion after only a few seconds of falling
- Bernoulli's Principle: Rotate fan ~30-45 degrees to either side

Equipment
Mini Fan, Balloon
