Introduction
The amount of fluid displaced when an object is immersed in it.
Pre-Requisites:
Buoyancy, Gravity, Density
Activity:
Attach a weight to hanging weighing balance. Fill a displacement can with water (till mark). Immerse the weight. You will observe a loss in the weight which is equal to the weight of the water displaced.
Real Life Question:
Think about what happens when you enter a bathtub/pool. Do you think the amount of water is equal to your weight?
