Forces in Fluids: Buoyancy and Density

The video tutorial explains the concept of buoyancy using a rubber duck as an example. It describes how buoyant force acts on submerged objects and how this force is influenced by the object's density. The tutorial further defines density as the mass per unit volume and illustrates how objects with different densities behave in water. The density of water is given as a reference point to determine whether objects will float or sink.

What happens to a rubber duck when it is pushed underwater and then released?

What is buoyant force and how does it affect submerged objects?

Explain the relationship between density and buoyancy.

Why does a rock sink while a rubber cork floats?

Define density and explain its significance in determining whether an object will float or sink.
