Basics of gravity and the Law of Universal Gravitation.

Light and the electromagnetic radiation spectrum. Wave and particle-like behaviour, and how to calculate the wavelength or frequency of a light wave.

Introduction to passive and active transport

An overview of what physics is about as we delve deeper in future videos. How physics is related to math, the other sciences, and the world around us. 

A discussion on how energy can't be created or destroyed in an isolated system, and works an example of how energy is transformed when a ball falls toward the Earth.

Three activities which illustrate the law of exponents.

This is a simple video which describes how indices problems are solved using simplified laws.

The beauty of a coral reef, the warm radiance of sunshine, the sting of sunburn, the X-ray revealing a broken bone, even microwave popcorn—all are brought to us by electromagnetic waves. The list of the various types of electromagnetic waves, ranging from radio transmission waves to nuclear gamma-ray (γ-ray) emissions, is interesting in itself.

Even more intriguing is that all of these different phenomena are manifestations of the same thing—electromagnetic waves (see Figure 15.1). What are electromagnetic waves? How are they created, and how do they travel? How can we understand their widely varying properties? What is the relationship between electric and magnetic effects? These and other questions will be explored.
