We all recognize what friction is, but do you really understand what causes it? This project focuses on friction, its causes and forces and specifically how it affects how fast you can slip down slides.

Explains the physics of building movement during an earthquake through a discussion of force, mass, acceleration, frequency, and period. Then looks at the factors that affect a building's resilience versus the damage it could sustain.

What is propulsion and how does it work? This NASA site provides an animated example plus many details related to its use in jet engines.

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.

This physics tutorial aims to model and predict not the motion of just one object, but rather what happens when two or more objects collide. The concept of momentum will be the main focus of this module.

Students learn about the Newtonian mechanics principle of conservation of angular momentum and the application in the quantum mechanical world.

Students explore the basic physics behind walking, and the design and engineering of shoes to accommodate different gaits. They are introduced to pressure, force and impulse as they relate to shoes, walking and running. Students learn...

Students apply their mathematics and team building skills to explore the concept of rocketry.Throughout the design process, teamwork is emphasized since the most successful launches occur when groups work effectively to generate creative...
