Aerodynamics of Cycling

It's important to make sure houses can withstand winds. A hands-on activity has learners create a structure out of household materials. They use a fan to simulate hurricane-force winds to see if their structures can withstand the...

Each of the slides here gives a definition, equation, or calculation example for a component of force and motion. This large collection covers topics from momentum and Newton's laws to centripetal forces and simple machines. Animations...

A massive star has a mass greater than nine times that of our sun. Sal focuses on the fusion and chemical reactions that take place during the lifecycle of a massive star. He clearly explains the gravitational pull to the chemical...

Using the Cartesian coordinate system, future flight experts plot points to determine whether or not an airplane will fly. With the four forces of weight, lift, drag, and thrust represented in different quadrants, your physics learners...

Are you studying or teaching Aerodynamics? This page acts as an index to all the terminology related to this topic. Clicking on any title will open a page with a colored slide and a scientific explanation of the contents. Animated,...

What a thrilling job for an engineer: designing advanced athletic competition suits! Which materials can most reduce friction and drag, and yet still be flexible enough to move with the athlete's body? With attention focused on Shani...

A detailed look at the aerodynamic principles associated with cycling. Good science and even better web page design. Includes an online calculator that allows the user to calculate the aerodynamic drag and propulsive power of a bicyclist...

Includes exhaustive information and a wealth of activities pertaining to aerodynamics and the physics of flight.

Young scholars learn about friction and drag - two different forces that convert energy of motion to heat. Both forces can act on a moving object and decrease its velocity. Students learn examples of friction and drag, and suggest ways...

How do airplanes fly? It's not magic. Learn about the forces that help (and hinder) airplane flight.
