Three demonstrations of polarization of charge are shown. A balloon polarizes a wall, small pieces of paper, and an aluminum can. The difference between conducting and inducting materials is presented.

An elastic collision is demonstrated and analyzed.

Translational and Rotational motion are demonstrated and reviewed. Torque is introduced via the equation and several door opening demonstrations. Moment arm or lever arm is defined and illustrated.

In January 1968, the start of the Tet Offensive by North Vietnamese communist troops sent waves of anger and anguish across the home front and sparked the most intense period of anti-war protests seen in the ‘60s. By this time, anti-war...

Mr.p pushes a shopping cart so you can learn about the physics concept of work!

Demonstrations of and Introduction to Conservation of Momentum

Six simple weather demonstrations you can do at home or at school to show the properties of air, using your hands and everyday materials.

The equation for the speed of a wave is derived. The fact that amplitude, frequency, and wavelength do not affect wave speed is demonstrated. Two different solutions for wave speed are demonstrated.

Sympathetic vibrations are demonstrated using pendulums of various lengths and a guitar.

AP Physics C: Electricity and Magnetism review of Capacitors including: demonstrating what capacitors are, defining capacitance, discharging a capacitor, deriving the capacitance of a parallel plate capacitor, defining dielectrics,...

An introduction to Rotational Equilibrium with a review of Translational Equilibrium and demonstrations. Wait there’s more … Static Equilibrium!

What happens when you drop a perfectly balanced stack of balls? And how is the result like a supernova? The classic momentum transfer demonstration, taken to the next level. A big thank you to my nephews and niece Drew, Max and Whitney...

The right hand rule for the direction of torque is described and demonstrated six times.

Learn about and see examples of Translational Equilibrium.

We experimentally determine the position, velocity and acceleration as a function of time for a street hockey puck that is sliding and slowing down. Is it uniformly accelerated motion?

The Law of Charges is demonstrated using a rubber balloon suspended from the ceiling. The net charge on an object via excess protons and electrons. Quarks as the constituent of protons and neutrons. Quantization of charge is...

Students sometimes have a difficult time understanding what acceleration in meters per second squared really means. Therefore, I present acceleration as meters per second every second instead. This helps students gain a better...

Charging by Conduction and Induction are both demonstrated. Each individual step is clearly described. Electrical Ground is introduced and defined. Both demonstrations are illustrated.

A problem involving forces on a wrench is used to determine the torque exerted by the wrench. A “cheater pipe” is also added.

Mini mr.p helps you learn about Gravitational Potential Energy with examples of different zero line locations.

Thank you to Arbor Scientific for letting me borrow their Rotational Inertia Demonstrator to … uh … demonstrate rotational inertia.

He was a fierce patriot and Founding Father – so why did John Adams defend British soldiers accused of murder following the Boston Massacre of 1770?

The Pearl Exchange is a hands-on experiential learning activity that shows how buyers and sellers determine equilibrium price in a market. It also shows how changes in a market will lead to shortages or surpluses and result in changes in...

In this video, I explain the Canadian C-spine rules, a guide to determining whether or not radiography is necessary prior to initiating physical therapy treatment.
