This activity is based on the common experiment of running a marble down a ramp to do work on a cup. Students will be able to see the relationship between mass and energy of the marble and the ramp height.

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

In this video, Peter Bohacek explains the interplay between work and power and how it can be seen in the functioning of a clock. [4:31] Followed by a short quiz and a list of additional resources to explore.

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...

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...

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,...

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...

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

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.

The activity investigates conservation of energy. Some topics explored are friction, kinetic energy, conservation of energy, and potential energy. The resource consists of video clips, lecture notes, practice problems, and exam...

This site from Georgia State University Physics Department defines and explains the concept of potential energy. Using equations and graphics to illustrate the idea, it discusses the many types of potential energy (gravitational,...

Demos and activities in this activity are intended to illustrate the basic concepts of energy science--work, force, energy, power etc., and the relationships among them. The "lecture" portion of the activity includes many demonstrations...

A collection of resources on how humans use machines and tools to meet their needs. Covers simple and complex machines, subsystems that transfer forces, mechanical advantage, speed ratio, the effect of friction, efficiency, the science...

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.

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

Students do work by lifting a known mass over a period of time. The mass and measured distance and time is used to calculate force, work, energy and power in metric units. The students' power is then compared to horse power and the power...
