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...

Basic definitions and examples for the concepts of work, energy, and power. Covers kinetic and potential energy, and conservation of energy.

To make sense of this, you have to first see the Twin Paradox: Introduction, which is the special relativity version and is linked to this page. This general relativity explanation views the paradox from a gravitational point of view.

Read about all the different kinds of potential and kinetic energy. Includes energy formulas and examples of energy applications.

Use animation and other interactive strategies to help understand physics principles. Change the track and height to see if your ball can make it to the end.

After creating three different ramps with various heights, students will release toy cars from the tops of each ramp. Based on the elementary age level, students will collect data and analyze it.

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.

This is a list of 74 problems/exercises to solve over the content of Chapter 7: Work, Energy, and Energy Resources from the AP Physics online text.

This is a glossary of words and definitions of terms having to do with work, energy, and energy resources.

For this activity, students learn about conservation of mechanical energy as they measure the velocity of a girl jumping on a trampoline using a direct measurement video with an embedded frame counter and ruler.

This unit has students design and build foam tubing roller coasters. The design process integrates energy concepts as they test and evaluate their designs that address the task as an engineer would. The goal is for students to understand...

Using marbles to construct a marble run, students will learn about projectile motion, kinetic energy, potential energy, final velocity, and forces.

This lab is designed to have students discover the relationship between the work that is done and the changes to height that occur to an object. Students can adjust the amount of energy added to the object. They can test five different...

In this interactive game, students match 17 terms related to energy with their definitions. These include the following: Kinetic, Sound, Potential, Elastic potential, Chemical, Gravitational Potential, Electrical, Light, Energy, Energy...

This set of interactive flashcards focuses on 17 terms related to energy and their definitions. These include the following types of energy: Kinetic, Sound, Potential, Elastic potential, Chemical, Gravitational Potential, Electrical,...

This virtual experiment is designed to let the student measure the relation between muzzle velocity (which determines projectile energy), gravitational potential and the effects of frictional drag caused by wind speed blowing opposite to...

Create a simplified roller coaster with this simulation by creating a track shape for a ball to travel on. Students can change gravity and damping. Site includes equations to help students understand what is happening in the simulation.

Take this ten question multiple choice quiz on energy in motion.

Fourth graders use a toy to make observations that speed is related to the amount of energy in an object as well as work with gravitational and elastic potential energy.

From ABC News in Science, Jennifer Viegas's article deals with social behavior of dogs and current research suggesting that they gravitate toward "winners." When they observe other animals or animal-human interaction, they go towards the...

A handy resource that gives an overview of equations and definitions pertinent to an introductory, college-level physics course, with two of its three sections focusing on motion-related topics and principles.

A narrated tutorial which illustrates how the work-energy theorem can be expanded to include other kinds of energy. [10:07]

Watch this screencast to understand the work-energy theorem in regards to energy. [8:45]
