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. 

These four short online lessons will cover the following:

• The planets of the solar system
• Planet orbits in the solar system
• Gravity in the solar system
• Inner vs outer planets

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.

This YouTube video will guide you through a fun activity where you will draw the earth's continents and oceans.

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.

An image that illustrates light reflecting off a plain mirror.

This online resource explores the following topics:

• Latitude and parallels
• Longitude and meridians
• Climate and latitude
• Time zones

An explanation of how LOL diagrams allow us to visually represent what we mean by conservation of energy as well as what we mean by an energy system.

Managing time involves accurately predicting how much time it will take to do a task, and then setting aside that amount of time to complete it. Managing time is much more difficult than it may seem, which is why there are entire courses of study and research on the best approaches. But if you develop a method to undertake each component, you’ll be successful.
