Work and Energy

The first activity may not work for your class if you don't have access to an open area of 30 meters and two cars of different masses, but the remaining activities can be used in any physics course. They all involve the investigation of...

A total of 29 word problems furnish practice in solving for work, energy, and force. A few of the questions display diagrams to help learners visualize the systems, and all of them list five choices from which they select the correct...

If you have a ticker tape, this activity will energize your future physicists. They push automobiles and measure the required force, then compare it to the distance and velocity recorded on the tape. Mini lab carts are also used to...

Your introductory physical science class will be energized by this PowerPoint. They will be able to define energy, work, and power. They will be able to perform calculations for kinetic and potential energy. They will be able to describe...

Planning a physics unit on energy can take a lot of work, luckily this instructional presentation is here to help. Covering everything from work and energy to elastic collisions and the conservation of momentum, this comprehensive...

Work, energy, and their relationship to power: what is the common thread? Explore this with your class as they learn the concepts of work and energy, both kinetic and potential, before completing multiple practice problems to demonstrate...

Everything around you is related to chemistry and more specifically, the energy within a system. The video explores how energy, in its different forms, changes after conversion — given off as heat or absorbed as heat  in chemical...

Start working with work and energy with your higher-level physics class. The narrator, Sal, starts off with defintions of the two terms, showing how they are related to one another. He then goes into an example and derives a formula for...

A NASA narrator and a cute cartoon-like character named Norbert demonstrate that applied force and distance of motion allow us to calculate work. The relationship between work and energy is explained. The difference between potential...

After reviewing the equation and terms from the previous video, Sal, the narrator, works through an example of an item that is fighting with the force of gravity. He introduces potential energy and begins to explain conservation of...
