Introduction to energy

Energy is defined as the ability to do work. Energy can be found in many things and can take different forms. For example, kinetic energy is the energy of motion, and potential energy is energy due to an object's position or structure. Energy is never lost, but it can be converted from one form to another.

Potential energy and position

The potential energy between two objects due to long-distance forces can be thought of as being stored in a field. When the objects move due to the field forces, the energy stored in the field decreases

Search for Open Educational Resources (OER)

According to Creative Commons there are over 1.6 billion openly licensed teaching and learning resources available on the internet. Open Educational Resources (OER) are quality, free educational resources, that you can use without having to ask for permission, and that can be adapted to better suit local contexts and needs.

Many educators and developers don't know how to efficiently search for and identity useful resources. Some throw up their hands in horror and give up when tasked with finding suitable resources on the Internet. In this tutorial, we are committed to providing you with a search strategy for open content to ensure that you quickly find open resources. Let us begin!

On completion of this unit of study you will be able to:

  • Decipher open licenses i.e. identify rights and permissions contained within Creative Commons licences attached to open content.
  • Search for open content using common tools and filters such as on Google Advanced Search and the YouTube Creative Commons filter, as well as specialized services such as Creative Commons Search to find open media.

What is energy?

Energy is a quantitative property of a system that depends on the motion and interactions of matter and radiation within that system. That there is a single quantity called energy is due to the fact that a system’s total energy is conserved, even as, within the system, energy is continually transferred from one object to another and between its various possible forms.
