A detailed explanation of the different types of forces that can be applied to an object and how to represent them in a free body diagram. Includes examples and some practice problems to try, with solutions provided.

In this unit, students will discover the period of time of one oscillation, the frequency of oscillation, the object displacement, its velocity, and its acceleration. They will also discover how to apply the principles of conservation of...

Great site explores the physics behind an electrical guitar. Outlines process for conducting an experiment on sound vibrations and provides animated GIF movies showing the first five modes of vibration.

Site tracks the vibrations of a drum and provides an animated movie.

The integrated circuit fueled the rise of microelectronics in the latter half of the twentieth century and paved the way for the Information Age. An American engineer, Jack Kilby, invented the integrated circuit in 1958, shortly after he...

This study information helps students apply Newton's third law and understand forces.

This article helps students understand and apply Newton's third law and the conservation of momentum.

Review how angular momentum is conserved if there is no external torque applied to a system. Specific scenarios are highlighted: system changing it rotational inertia, orbiting bodies, and rotational collisions.
