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 ...

This resource is suitable for energy and sustainability topics for primary school learners. Aw, he's always sleepy after a walk… but the potential is there. See, energy can't be created or destroyed.

Suppose we consider the incline to be smooth. In this case, there is no work done on the system by non-conservative forces. Consider the simulation results below of the block sliding on a smooth ...

JONNY NELSON: Energy. There are lots of different types and lots of different ways of storing it. Chemical energy in a sparkler, elastic potential energy that fires a toy into the air, and many, many ...

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 ...
