Energy is stored. For example, energy is stored in the kinetic energy store in objects that move. When we pay for an item in a shop we are transferring our money from one store (pocket, purse or wallet) to another (the till). Energy can be transferred between different stores. In the United Kingdom, money is measured in pounds sterling (£).
Moving objects store energy in their kinetic energy store. elastic potential energy store. A hot object has more energy in its thermal energy store than when it is cold. The energy in the nucleus of an atom is in the nuclear energy store. Food, batteries and fuels store energy in their chemical energy stores.
Energy is transferred from the gravitational store to the kinetic store of the object via a mechanical transfer pathway Don't worry too much about the parameters of the system. They are there to help you keep your answers concise so you don't end up wasting time in your exam.
There are four ways that energy can be transferred between stores: electrically, by heating, mechanically and by radiation. An energy pathway describes the stores that energy is transferred between and how it is transferred. Energy pathways can be represented with diagrams that look like the one below.
The energy in the nuclear store can be released by radioactive decay. The internal store of energy is the sum of the kinetic energy stored in the particles of an object and the chemical energy stored in chemical bonds between particles in the object. Energy can be stored in a system in lots of different ways. Some stores of energy are:
energy Energy can be stored and transferred. Energy is a conserved quantity. can be described as being in different ‘stores’. Energy cannot be created or destroyed. Energy can be transferred from one store to another. What is energy? Energy is a quantity that is conserved - it cannot be created or destroyed. Energy can be stored and transferred.
