From a chapter on Statics and Torque in a Physics textbook. This section of the chapter provides an in-depth discussion of forces and torque in the human body. We learn about muscular force, the importance of posture in preventing back...

By the end of this section, you will be able to define conservative force, potential energy, and mechanical energy; explain the potential energy of a spring in terms of its compression when Hooke's law applies; and use the work-energy...

By the end of this section, you will be able to define nonconservative forces and explain how they affect mechanical energy, and to show how the principle of conservation of energy can be applied by treating the conservative forces in...

In the following interactive students will begin to explain how an object must be displaced for a force on it to do work. They will also explain how relative directions of force and displacement determine whether the work done is...

In this lesson, the students will work across the curriculum using technology, business education, and mathematics. They will form a company and use the physics of force and motion to build a hovercraft. The students will use this...

In the following interactive students will begin to define nonconservative forces and explain how they affect mechanical energy. They will show how the principle of conservation of energy can be applied by treating the conservative...

What keeps you in your seat of a giant loop-de-loop roller coaster? Surprisingly, it is not the seatbelt but the seat. It works because of something called centripetal force and it does much more than make a great roller coaster. In this...

[Free Registration/Login Required] This module has students using a simple machine to learn about the relationship between work, force, and energy.

[Free Registration/Login Required] An informational text about how a compass works using electromagnetic force. A question sheet is available to help students build skills in reading comprehension.

[Free Registration/Login may be required to access all resource tools.] In this online lesson students will learn to calculate work and explain how it relates to the overarching idea of energy.

This is a summary of the information in Chapter 7: Work, Energy, and Energy Resources for the AP Physics I course online.

By the end of this section, you will be able to explain work as a transfer of energy and net work as the work done by the net force and to explain and apply the work-energy theorem.

This lab is designed to have students discover the relationship between the work that is done by a force and the speed gained by the object experiencing the force. Students can adjust the strength of the force. They can decide how much...

Through illustrated examples and interactive examples, students learn about the two categories of forces are referred to as internal forces and external forces.

[Free Registration/Login may be required to access all resource tools.] How to calculate work from force and distance and vice versa, and the SI unit for work.

[Free Registration/Login may be required to access all resource tools.] Definition of work and how it relates to force and distance.

By the end of this section, you will be able to explain how an object must be displaced for a force on it to do work; explain how relative directions of force and displacement of an object; and determine whether the work done on the...

[Free Registration/Login Required] A video module where students learn about the relationship between force, work, energy, and mechanical advantage using a simple machine.

In the following interactive students will begin to explain work as a transfer of energy and net work as the work done by the net force. They will also explain and apply the work-energy theorem.

By the end of this section, you will be able to explain gravitational potential energy in terms of work done against gravity, show that the gravitational potential energy of an object of mass m at height h on Earth is given by PEg = mgh,...

This page explores the quantitative relationship between work and mechanical energy in situations in which there are no external forces doing work. It is a basic analysis of situations in which mechanical energy is conserved. Examples...

[Free Registration/Login may be required to access all resource tools.] In this module, calculate work and explain how it relates to the overarching idea of energy.

Describes the definition and relationships between force, work and power. Includes nice drawings to increase conceptual understanding.

Investigating a waterwheel illustrates to students the physical properties of energy. They learn that the concept of work, force acting over a distance, differs from power, which is defined as force acting over a distance over some...
