The difference between wave and object interaction is demonstrated. Constructive interference, destructive interference, and total destructive interference via superposition are all demonstrated.

When a point particle collides with a rigid object with shape which is allowed to rotate on a stationary axis, is linear momentum of the system conserved? Is angular momentum of the system conserved? These questions are answered using...

Ian Terry, winner of Big Brother 14, makes a special appearance to help us learn about Conservation of Mechanical Energy. See several demonstrations and understand when mechanical energy is conserved.

This video introduces an Art Assignment perfect for Middle and High School students needing motivation to practice still life drawing. Mixed Media Still Life Drawing adds voice and choice to a "boring" still life!

Doppler Effect in One Minute

An introduction to the physics equation for work, including a few basic examples of positive vs. negative work.

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

Learn why a centripetal force exists, three important things to remember about centripetal force, and drawing free body diagrams for objects moving in circles.

Resonance is introduced and demonstrated using a “singing rod”, a swing, a goblet, a hollow tube in water, a hollow tube open on both ends, a seashell, a broken speaker, a human body and a key fob, and a shorter “singing rod”....

Air and moisture in different quantities comprise our atmosphere. The sun is the energy source that causes temperature change, wind, clouds, rain, dew, blue skies and rainbows. See how to build an instrument called a "sling psychrometer"...

Weather lessons come alive for students in simple experiments and demonstrations. Kids show the basic principles of weather in these easy experiments and demonstrations. Using everyday materials, watch how to make a tornado in a bottle....

Four mechanical wave graphs are introduced and used to understand and demonstrate transverse waves, longitudinal waves, wavelength, and period.

An introduction to mechanical waves which are defined and demonstrated. The fact that the medium is not displaced is demonstrated. Both transverse waves and longitudinal waves are also defined and demonstrated.

How rainbows create their colors, in refraction.

Defining Force. Including its dimensions, demonstrations of force and mass affecting acceleration, showing that a force is an interaction between two objects and contact vs. field forces.
