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?

• 0.93 newtons

• 0.80 newtons

• 1.72 newtons

• 2.00 newtons

What is the measured force required to keep the wood cylinder submerged?

• 1.00 newtons

• 0.80 newtons

• 0.93 newtons

• 1.72 newtons

Why is there a difference between the calculated buoyant force and the measured force?

• The buoyant force is less than the gravitational force.

• The buoyant force is greater than the gravitational force.

• The gravitational force is subtracted from the buoyant force.

• The forces are equal.

What is the gravitational force acting on the wood cylinder?

• 0.93 newtons

• 1.00 newtons

• 1.72 newtons

• 0.80 newtons

How does the calculated force to hold the cylinder underwater compare to the measured force?

• It is significantly higher.

• It is exactly the same.

• It is significantly lower.

• It is almost the same.
