Technology can help save money and add convenience. The resource offers a free textbook for a complete Chemistry course. The text begins with a review of the scientific method and continues to explain topics such as chemical bonding,...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

Textbooks come in all shapes, sizes, and media these days. An electronic textbook resource offers Physics materials for an entire course. The text offers an explanation of physics topics as well as examples of calculations and reading...

From a chapter on Rotational Motion and Angular Momentum in a Physics textbook. This section of the chapter discusses developing an equation for rotational work, how to determine the rotational kinetic energy along with a problem-solving...

This resource examines how to determine the maximum speed of an oscillating system. It discusses how the concept of law of energy can be applied in solving these types of problems.

From a chapter on work and energy in a Physics textbook. This section of the chapter covers the difference between renewable and nonrenewable energy resources, the growth in the world's energy consumption, and the link between energy use...

Using a roller coaster as an example, the transformation of mechanical energy from the form of potential to the form of kinetic and vice versa is explained and illustrated in the animation.

Find out about the first and second laws of thermodynamics, and how they relate to the biology of life.

In this interactive exercise, explore the quantitative relationship between work and mechanical energy in situations in which there are no external forces doing work.

Through illustrated examples and practice problems, students apply the relationship between work and mechanical energy change to a variety of motion scenarios in order to test our understanding.

Consider an ordinary dart projected from a toy dart gun and moving through the air. Students analyze work and energy of the motion of the dart with this animation.

This site from NASA states Kepler's second law of planetary motion and depicts its meaning with an informative diagram. Relates the law to conservation of energy principles and discusses the eccentricity of a satellite's (or a planet's)...

A page from the Fundamentals of Physical Geography site. Identifies, describes and elaborates upon the first, second, and third laws of thermodynamics.

Demonstrates how principles of kinetic energy, potential energy and energy conservation can be used to determine the speed of a descending object if given its initial height. Further discussion of other topics such as heat and...
