Conceptual Physics Alive: Center of Gravity includes a digital video and questions set with answers.

Observe Paul Hewitt teach in a classroom with real students, using engaging demonstrations and artwork. In this video, Paul Hewitt teaches Center of Gravity: The concepts of torque, center of gravity, and center of mass are applied to balancing. Demonstrations include finding the center of gravity of irregularly-shaped objects, a weighted disk that rolls uphill, and a seesaw.

Center of Gravity Includes:

• Begins by Hewitt throwing a ball and wooden object through the air to introduce center of gravity (CG) and center of mass.
• Center of gravity of L-shaped wood and irregular piece of wood found by suspension technique.
• Hewitt demonstrates the toppling of L-shaped wood and introduces the concept of torque.
• The CG of people is discussed.
• Hewitt demonstrates the impossibility of toe touching with heels to the wall, with a follow-up chalkboard explanation.
• Pregnant lady and CG skit.
• CG examples: pigeon walk, monkeys, and dinosaur tail.
• Trucks on a hill are sketched on board to illustrate CG.
• Demonstration of a 'loaded' disk rolling up an incline.
• Seesaws, CG, and torque.
• Solitary seesaw discussed.
• Hewitt saws a broom in half at its CG.
