Abstract

Resource Image We offer data from a physical experiment in which the depth of a container in water is measured and ask students to build a model of buoyancy based on Newton's Second Law of Motion and a Free Body Diagram. We ask students to estimate the parameters.

Description

We have all experienced buoyancy, be it with our little rubber ducky when we were in the tub or floating in the ocean or bobbing for apples (they did not sink). Can we model a bouncing or bobbing object in water though?

Let us consider an object floating in water. We press it down and it bobs back up, and then down, and then up, and then down, etc. until it comes to rest in the wavy water around it, caused by its own up and down motion.
