Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time....

By taking a look at the energy of motion all around us, students learn about the types of energy and their characteristics. They first learn about the two simplest forms of mechanical energy: kinetic and potential energy, as illustrated...

Have you ever been assigned a chapter to read for homework? After you finish you may think to yourself, "That was a lot of work!" You might be surprised to learn that in the scientific sense, reading a chapter is not work at all!In...

A very detailed look at gravitational force and the many theories that have been put forward to try to explain it. Includes lots of illustrations.

A collection of experiments where students can learn about how friction works and affects the physical world. At the end, students design a tortoise to win by slowing it down using friction. Lesson includes explanation of the concept of...

This is a performance task for Grade Four students where they observe two different pendulums and compare the two types of motion. The activity is designed for a lab setting where students work at individual stations. A rubric and...

Displays images by photojournalist, Sebastian Salgado, on immigrants in motion "seeking survival and a better life - one individual at a time, one family at a time, from field to town to city, and across national boundaries"....

With a simple demonstration activity, students are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Then, in the Associated Activity (Sliding and Stuttering), they work in teams to...

Article attempts to answer the question "what is Physics?" Takes a look at concepts such as force, motion, Newton's Laws, work, energy, and much more.
