Access Code (located on the underside of the lid of your lab kit): AC-8
Lab Report Format Expectations
Utilize college level grammar and formatting when answering text based questions.
Report all equations in a proper mathematical format, with the correct signs and symbols.
Submissions with incomplete or improperly formatted responses may be rejected.
Pre-Lab Questions
1. Archimedes' principle is a fundamental concept in fluid mechanics and relates directly to the
buoyant force. Archimedes' principle states that:
"Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of
the fluid displaced by the object."
In your own words, explain the Buoyant Force as it relates to Archimedes Principle. Ensure that you
discuss this in terms of the equation for Buoyant Force.
The force is equal to the weight of the fluid that the object displaces. The greater the volume of
displaced fluid means the greater the buoyant force acting on the object. If the buoyant force is
greater than the weight the object floats. If the buoyant force is equal to the objects weight it
remains in place. If the buoyant force is less than the onbjects weight, it sinks.

2. Draw a free body diagram of a hanging mass before it is submerged in water. Make sure to label
your forces and include your handwritten name in the background.
