Inertia P.E.O.E. Demonstrations – submitted by Michael Balzer

The link below takes you to two very useful demonstrations to illustrate Inertial which follow the Predict, Explain, Observe, Explain (PEOE) format.

It is suggested that both demos are performed before introducing Newton’s First Law of motion.

World’s First Car! and Car Safety- Veritasium

Physics is something that is directly applicable to car safety. Cars go fast, but they also sometimes collide with obstacles, which brings them to a sudden stop, subjecting the car and occupants to very high accelerations, which can cause injury or death. So the major idea to improve car safety is to reduce these accelerations and there are a number of ways to do this: Continue reading

The physics of the “hardest move” in ballet – Arleen Sugano

In the third act of “Swan Lake”, the Black Swan pulls off a seemingly endless series of turns, bobbing up and down on one pointed foot and spinning around and around and around … thirty-two times. How is this move — which is called a fouetté — even possible? Arleen Sugano unravels the physics of this famous ballet move.
