Forces and energy: Quantum energy

Checking out Einstein and going quantum Quantum and classical physics both have the concept of energy in common. The conservation of energy still applies in quantum physics the same way it does in classical physics. The difference is in the math used to calculate energy and work. In quantum physics it is all about probability – the energy something has ...

Forces and energy: Electricity and sustainable energy

Electrical energy Electrical energy also has many forms. For example, lightning, is a form of static electricity. You witness static electricity also when you rub a balloon against your hair. One of the most useful forms of electrical energy for humans is when it is generated from a current, which occurs when electrons flow through a circuit. It is the ...

Forces and energy: Kinetic, potential, conservation and transformation

Forms of energy The two broad forms of energy are potential and kinetic and each have different types, which we outline in more detail below. Others energy forms include sound and thermal energy. We will focus on potential and kinetic here. Light could also be considered a form of energy, but it gets interesting because is has both particle and ...

Catapult

Make a simple catapult that can fire small items across rooms. Students can invent games to play and experiment with their catapults and test their understanding of potential and kinetic energy. Learning Intentions Students will use the scientific process identify and understand potential and kinetic energy, their use to do work and how energy can be transferred from one form …
