Module 3: Motion Commotion

A Study of Forces and Movement

Description
In this module students will learn some of the basic concepts of mechanics, how the skeleto-muscular system works, and how various kinds of materials resist tension and compression. These concepts will be explored in the context of animal and vehicular motion. Students will study the role of forces in acceleration and friction, how engines convert chemical bond energy to kinetic energy, the origin of ocean currents, and the meaning of tensile and compressive strength.
