Authored and curated by David P. Stern, this series of web pages, part of "From Stargazers to Starships," describes Newton's three laws of motion and the two concepts on which they are based, force and inertia. The...

This lesson introduces students to Sir Isaac Newton's Second Law of Motion. Topics include the two ways to study the dynamics of a system in which there is motion, a brief description of Newton's work in studying and...

This simulation provides a realistic virtual mass-and-spring laboratory. Users can explore spring motion by manipulating stiffness of the spring and mass of the hanging weight. Concepts of Hooke's Law and elastic...

This item is a high school-level assessment to gauge understanding of using diagrams to predict outcomes in systems set to collide. It is intended for use within a unit on the conservation of linear momentum. The...

The Materials Science and Technology Teacher's Workshop (MAST) provides this activity to illustrate the principles of energy transfer. The demonstration uses a balance, matches, soda cans and a firecracker to show how...
