Experiment 3- Buoyancy

Question 1

When we jump into the swimming pool, we feel lighter; this is due to the ______ force.

Answer 1

Buoyant.

Question 2

When an object is completely submerged in fluid, what parts of it is experiencing pressure from the fluid?

Answer 2

All parts.

Question 3

How does fluid pressure get affected with increasing depth?

Answer 3

It gets larger.

Question 4

What is the equation for calculating net buoyant force?

Answer 4

FB= F bottom- F top= p fluid . G. A (H2-H1)= p fluid. G. V displaced , where V displaced is the volume of the fluid displaced by the object.

Question 5

With the experimental apparatus, what is the force sensor able to measure? How does this value change as the object is lowered into the water?

Answer 5

It’s only able to measure the force pulling down on the object. As it is submerged, the magnitude of the measured force decreases since there will be a buoyant force acting on the object.
