Buoyant Force on a Submerged Wood Cylinder Explained

The video tutorial explains how to calculate the buoyant force acting on a wood cylinder submerged in water, which is approximately 1.72 newtons. It then compares this with the measured force needed to hold the cylinder underwater, which is about 0.80 newtons. The tutorial clarifies that the force required to keep the cylinder submerged is the buoyant force minus the gravitational force on the cylinder, calculated to be around 0.79 newtons, closely matching the measured value.

What is the calculated buoyant force acting on the wood cylinder?

What is the measured force that holds the wood cylinder under the water?

How does the magnitude of the force necessary to hold the wood cylinder relate to the buoyant force and the force of gravity?

What is the difference between the buoyant force and the force of gravity acting on the wood cylinder?

Why is the measured force of roughly 0.80 newtons considered satisfactory in relation to the calculated values?
