Why Do Flamingos Stand on One Leg?
It seems like kind of an awkward way to spend most of your time, but flamingos seem perfectly happy to hang out on one leg. For a long time, people assumed they were trying to conserve heat. But thanks to some unusual research, we now...

Center of Mass
In this video Paul Andersen explains how the center of mass of an object represents the average position of matter in an object. The center of mass of a system is a combination of all the objects within the system. As long as no external...

Finding Centre of the Mass of a Ruler
We are trying a fun way to find the centre of the mass of a ruler. If you hold your index fingers in front of you, put a ruler on top of them and start moving your hands towards each other, your fingers end up right at the unique point...

Calculating the Center of Mass of a System of Particles
Three point objects are located at various locations on a Cartesian coordinate system. Mass 1, with a mass of 1.1 kg, is located at (1.0,1.5) m. Mass 2, with a mass of 3.4 kg, is located at (3.0,1.0) m. Mass 3, with a mass of 1.3 kg, is...

Center of Mass Introduction
Center of mass is defined and demonstrated in projectile motion. We demonstrate what happens when you push at or near the center of mass. The center of mass of a Feeble is demonstrated. And the “Hang Test” is used to find the center of...

Study Jams! Gravity & Inertia
Is it possible to defy gravity? Not really. With force and inertia, we can act against it for a little while, but, eventually, gravitational force will pull us back to Earth. The relationships among mass, force, and inertia are all...

Bozeman Science: Gravitational Forces
Award-winning science teacher Paul Andersen helps make physics understandable as he explains how gravitational forces differ from the other three fundamental forces: electromagnetic, and strong and weak nuclear forces. [5:05]
National Science Foundation
National Science Foundation: Science of Speed: Load Transfer
The corners of a NASCAR track are divided into three parts because the car's grip changes in different parts of the turn. A race crew must try to minimize load transfer by making adjustments based on a car's centre of gravity. [5:05]

National Science Foundation: Science of Speed: Balance
Getting the right balance in a race car is difficult because the weight of the fuel changes as the fuel burns off, and the tires wear down during each green-flag run. [5:16]
