Buoyant Force in Action: Weight of Displaced Water!

The video tutorial explains the concept of buoyant force as the weight of the fluid displaced by an object. It demonstrates the changes in tension force when a rock is submerged in water, using a force sensor to measure these changes. The tutorial also covers the water displacement method to determine the volume of an irregularly shaped object and calculates its density. The experiment validates the principle that the buoyant force equals the weight of the displaced fluid, with a minor discrepancy in measurements.
