In this video, we break down the math behind centripetal acceleration in circular motion. From the basics to the formula, we’ll show you how acceleration works when an object moves in a circle! #Centr ...

Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. For example, in order to lift a heavy object, we must do work to overcome ...

The story “The Motion of Molecules Makes Electricity,” dated Oct. 23, 2023 (page 7), highlighted a recent paper published inAPL Materials by Luan et al. that purports to demonstrate the harvesting of ...

The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, ...

Michael Graham Richard is a writer from Ottawa, Ontario. He worked for Treehugger for 11 years, covering science, technology, and transportation. So what is kinetic energy? There's motion everywhere ...

Fluid filled with lively, churning bacteria could one day become a small-scale power source. New computer simulations indicate that a miniature wind farm‒like device could harvest the energy of ...

Sleepwalking through your job? Often hit by the 2 p.m. slump? A new study suggests a quick fix for those daily lags in energy. And no, it’s not a cup of coffee. Interspersing short movements and ...

Maria Keane (MSES ‘22) considers her job more of a calling than a career. Keane is the senior circular economy technical manager at Energetics, a full-service technical and management consulting ...
