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...

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.

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.

Using diagrams, illustrations, and relevant data, students will calculate the net work done on an object, the change in an object's velocity, and the change in an object's kinetic energy.

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,...

By taking a look at the energy of motion all around us, students learn about the types of energy and their characteristics. They first learn about the two simplest forms of mechanical energy: kinetic and potential energy, as illustrated...

[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.

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.

In this hands-on activity - rolling a ball down an incline and having it collide into a cup - the concepts of mechanical energy, work and power, momentum, and friction are all demonstrated. During the activity, students take measurements...

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,...

The orbits of satellites are described and an energy analysis is performed. Kinetic, potential and total mechanical energy are explained and applied to the motion of satellites.

In this interactive module, students learn the basic terminology and concepts of power as it has to do with work and energy.

See how motion is converted and the energy associated with the motion is used to do work.

In this activity, Students can use a Force Sensor to measure the force needed to lift an object and the force needed to pull the same object up an inclined plane. They will also calculate work done and efficiency and make conclusions.

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

Teams of students design, build, test, and evaluate a working watermill made from everyday materials. Lesson explores how watermills generate energy from water, while students gain an understanding of the structural engineering design...

Through interactive practice problems and examples, students calculate the amount of work done by forces.

Through interactive exercises and illustrated examples, students analyze situations involving external forces.

Here you can learn all about heat flow, one of the major driving forces of nature, and how it works. It is the force behind weather, photosynthesis, animal behavior, and much more.

Looking to review how kinetic energy is related to mass and speed? This video lesson review the concept of kinetic energy, mass, and speed with both definitions and problems. Problems are work through step-by-step so you can review how...

[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.
