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 buoyant force is the upward force exerted by a fluid on an object that is either fully or partially
submerged in it. According to Archimedes’ Principle, this force is equal to the weight of the fluid
displaced by the object. In other words, when an object is placed in a fluid, it pushes some of the
fluid out of the way, and the fluid responds by pushing back with an upward force. This force can be
calculated using the equation for buoyant force: Fb=ρVgF_b = \rho V gFb=ρVg, where ρ\rhoρ
represents the density of the fluid, VVV is the volume of fluid displaced, and ggg is the acceleration
due to gravity. If the buoyant force is greater than the object's weight, the object will rise; if it is less,
the object will sink. This principle explains why objects float more easily in denser fluids and why
ships made of heavy materials can still stay afloat by displacing a large volume of water.

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.
