F2-21 REACTION TO BUOYANT FORCE
- ID Code: F2-21
- Purpose: Demonstrates the reaction force using a liquid.
- Description: A beaker of water is balanced by two brass weights. Stick your finger into the water about up to the first knuckle, the water side will go down. The water exerts a buoyant force on your finger, so your finger exerts a reaction to the buoyant force on the water, thereby causing the water side to go down.
