If light things float why do they sink?
In this chapter, we will explore the basic physics behind boats and things that float. As with the chapters on sports and car simulations, we'll start armed with an understanding of Newtonian mechanics and kinematics. The concepts of force, acceleration, torque, and velocity apply just as ...

Objects float when the volume of water they displace is less than the volume of the objects themselves. When objects sink, the volume of water they displace is greater than the volume of the object. The principle may seem relatively simple: Light objects float and heavy objects sink. However...
