Revision of Energy stores and transfers for GCSE Physics/Combined Science. Energy stores . There are 8 energy stores where energy can be ‘kept’: – chemical store (in a chemical reaction e.g. fuel + oxygen) – kinetic store (in a moving object) – gravitational store (due to the position of an object in a gravitational field) – elastic ...
Examples of Energy Changes. Flying – an object projected upwards. When an object is projected upwards, such as a ball, it will initially have kinetic energy (KE).As the object rises higher into the air, the kinetic energy will be transferred into gravitational potential energy (GPE).Once the object reaches its highest point, the gravitational potential energy will all be converted into ...
Calculating Changes in Energy. Understanding energy transformations involves some calculations. Here are formulas for the main energy stores: Kinetic Energy (KE): KE = 1/2 mv^2 where m is mass in kilograms and v is velocity in meters per second. Gravitational Potential Energy (GPE): GPE = mgh where m is mass, g is the acceleration due to gravity (9.8m/s^2 on Earth), and h is height in meters.
AQA GCSE Energy stores and Systems (Physics) Systems A system is an object, or group of objects. This bowl of soup is an example of a system. There are 3 main types of system:1. Closed System2. Open System3. Isolated System Closed SystemEnergy can enter or leave the systemParticles or matter cannot enter or leave the system Open
Step 2: Determine the store that energy is transferred to When the circuit is closed, the bulb lights up. Therefore, energy is transferred to the thermal store of the bulb. Energy is then transferred from the bulb to the surroundings, but this is not described in the parameters of the system. Step 3: Determine the transfer pathway
Energy Stores. There are eight different energy stores which might be mentioned in your GCSE: Chemical store of energy, for example batteries and food; Gravitational store of energy, for example any object that can fall such as a aeroplane or a ball that has been thrown; Kinetic store of energy, for example any object that is moving such as a ...
When you describe the changes in energy stores for a scenario, you must break the problem down into three parts: Choose a clear start and end point. Decide which energy stores are involved in the process. Name the transfer processes that take place between the stores
Energy: Energy Stores & Systems Energy: Energy Stores & Systems. Energy Stores. Energy is the capacity to do work and it can be stored in various forms.. Energy may be stored in kinetic, thermal, chemical, or nuclear stores when work is done on the system.. Gravitational potential, elastic potential, electrostatic, and magnetic stores are energy stores related to an object’s position in a ...
The books that are higher on the bookshelf will have a higher store of gravitational potential energy than the books lower down on the shelves. Elastic Potential Energy. Elastic potential energy is stored when exerting force to deform an elastic object. If we compress a spring, then it will have a large store of elastic potential energy.
Importance of Energy Stores in GCSE Physics. Understanding energy stores is key to making sense of how different systems work. It helps you break down complex processes and track where energy starts, how it moves, and where it ends up. This approach makes it easier to understand physical systems and spot energy transfers.

GCSE; OCR Gateway; Energy stores and transfers - OCR Gateway Energy. Energy can be described as being in different 'stores'. It cannot be created or destroyed but it can be transferred, dissipated ...
Describing energy transfers in systems such as roller coasters and pendulums. Stating the principle of conservation of energy: energy cannot be created or destroyed, only transferred, stored, or dissipated. Exploring energy dissipation as wasted energy transferred to the thermal store of the surroundings. Resource features:
