The Work Energy Principle is one of the big ideas in introductory physics courses. It's so big that the textbook presentation can get a little confusing - but it doesn't have to be that way. I haven't ...

Kinetic weapons shoot bullets. That may seem fairly reductive considering the space guns of Destiny 2, but these bullets have a special purpose. Kinetic weapons are there to take down your enemy’s ...

People power is perhaps one of the world's greatest untapped sources of renewable energy. Smart devices that harness kinetic energy from everyday human activities help the environment in more ways ...

Potential energy is the latent energy in an object at rest, and is one of two forms of energy. The other form, kinetic energy, is the energy expressed by an object in motion. Potential energy is a ...

As a consulting mechanical engineer, I assessed more than 400 crash tests for the Australasian New Car Assessment Program from 1996 to 2017. It is always interesting to answer questions like this. The ...

We define and explain mathematically through multiple example problems. Segment 4E: Gravitational Potential and Kinetic Energy Gravitational potential energy and kinetic energy are defined and ...

Based out of the Netherlands, Energy Floors creates clean and renewable energy-producing systems that are activated by movement. Dance, walk and compete your way towards creating energy that then runs ...

A flywheel is a very heavy wheel, formerly a large spoked wheel with a heavy metal rim but now more commonly made from a carbon-fiber composite material, with a smaller cylindrical form that is only ...

Water wheels, racers, and wrecking balls. Mechanical energy is the combined potential and kinetic energy in an object that enables work to occur through the movement of another object. Learn how ...

Researchers at Columbia University have conducted the first exhaustive study into kinetic energy harvesting -- the harvesting of "free" energy from common human activities, such as walking, writing ...

This resource is part of Science Friday’s Educator Phenomena Forum and was developed collaboratively by Jose Rivas, an engineering and AP science teacher in Lennox, California, and Sarah Han, a PhD ...
