Have you ever tried to walk across a flowing stream? Have you ever watched a news report that showed cars and bridges being washed away by a flood? These experiences and events suggest the force of moving water, which provides a...

In this lesson, students learn about work as defined by physical science and see that work is made easier through the use of simple machines. Already encountering simple machines everyday, students will be alerted to their widespread...

Learn about elasticity and how to determine the force exerted by a spring.

Explore forces, energy, and work as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces acting on the file cabinet. Graphs show forces, energy and work.

Provides a long list of physics formulas for easy reference.

Simple machines such as inclined planes in wedges and screws are explained.

This site examines the black hole as an object in astrophysics. Delve into this comprehensive resource that covers this concept from its history, to qualitative physics, the reality of black holes, mathematical physics and more.

A handy resource that gives an overview of equations and definitions pertinent to an introductory, college-level physics course, with two of its three sections focusing on motion-related topics and principles.

This lesson plan will allow students in groups to describe the relationship between energy, work, and force through the use of pendulums. The results will be reported through a graphing activity as well as a paragraph written and printed...

Take an interactive quiz over physical science careers. After completing the quiz, check your score, and then revisit any incorrect question for further review.

This site from The Museum of Science presents some compound machines and asks students to identify which simple machines they are composed of. Students provide their answer and receive immediate feedback.

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.
