These days everyone seems to be talking about energy, whether it’s the rising cost of electricity, gas and petrol, carbon costs and offsets, alternatives to our traditional sources or what happens when the oil finally runs out. Going a little bit deeper, however, and trying to get to grips with [...]

What is Potential Energy?

There is a school of thought that classifies all energy as either potential energy or kinetic energy. Other scientists dislike this division, arguing that it is artificial; however, the terms ‘potential energy’ and ‘kinetic energy’ are frequently used, so it is important to understand what they mean. Kinetic Energy Of [...]

Light and Sound Waves Explained

By |2021-05-25T19:25:46+00:00November 3, 2008|What is energy|

Light travels in waves, and sound travels in waves. However, sound waves and light waves are very different, and it is important not to confuse the two. Light travels in electromagnetic waves, and sound does not. Sound waves are caused by vibration. Electromagnetic Radiation One way in which energy can [...]

All About How We Measure Energy

By |2021-05-25T19:25:46+00:00November 3, 2008|What is energy|

How We Measure Energy A good definition of energy is ‘the ability to do work’. When we measure energy, what we want to know is: how much energy was required to achieve certain results? Joules Finding a method of measuring energy that would enable meaningful comparisons to be made between [...]
