How does that bridge stay up? What are the forces acting on that column? This site helps students understand how structures can be built by having them build their own. Also provides images of real structures for kids to compare with...

You're in a bubble and that pointy thing in each level is your only ticket to freedom. Don't let any obstacles stand in your way!

This presentation explains why a poorly defined system can lead to incorrect answers in physics problems.

This illustration provides an overview of the scientific process of when a skydiver steps out of a plane.

Use this outline to find out about Newton's Laws of Motion. Use the different lesson plans covering the laws of motion to learn more.

Students investigate a variety of applications of circular motion principles to the world of sports, and use Newton's laws to mathematically analyze such motions. The emphasis will not be upon an investigation of the details of every...

In UCM, the net force called Fc is equal to mv2/r and is directed toward the center. This is demonstrated by an object that is suspended by a string and is moving in a circular path which makes a conical pendulum. In this experiment, you...

By the end of this section, you will be able to explain work as a transfer of energy and net work as the work done by the net force and to explain and apply the work-energy theorem.

Students begin to explore the meaning of Newton's Second Law of Motion by doing several self-checking practice problems.

Students must determine the net torque on a wheel. There will be four forces on the wheel and all of them will be at right angles to the radius from the center of the wheel.

Students must determine the net torque on a wheel. There will be two forces on the wheel that will be apply at random angles to their radii.

[Free Registration/Login may be required to access all resource tools.] The laws that govern interactions between charged particles are explained, and methods of creating a net charge on an object are described.

An interactive Java applet where users can rotate a vector about its tail and view the components of that vector. Magnitude of the components is updated on screen as the vector is dragged.

Newton's First Law also called the law of inertia is the most important thing to realize about motion. This article offers more information on motion and explains solved problems involving Newton's First Law. Also included is a video...

A complete lab where a student verifies the force versus distance relationship of Coulomb's Law.

Through informational text, interactive activities, practice problems, online labs, virtual simulations, and video clips, students learn about Newton's Laws of Motion.

By the end of this section, you will be able to define mass and inertia and to understand Newton's First Law of Motion: There exists an inertial frame of reference such that a body at rest remains at rest, or, if in motion, remains in...

The wind blowing over your house, the Gulf Stream flowing into the North Atlantic Ocean from Florida to Europe, the jet stream at 10 km altitude. All these different flows in the atmosphere and in the ocean can be understood using ideas...

Overview of the key terms and skills related to electric charge, including how to calculate net charge.
