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.

Describe how the tension force changes as the rock is lowered into the water.

Explain how the buoyant force changes when the rock is submerged in water.

What is the significance of the negative reading on the force sensor when measuring the buoyant force?

What is the relationship between the buoyant force and the weight of the fluid displaced by the object?
