Energy can be transferred from one store to another in four ways: Mechanical work – a force is applied to move an object, for example when a person lifts a book onto a high shelf.

3 lip 2024 · The relevant energy transfer is from the thermal store of the kettle to the thermal store of the water, with some energy dissipated to the surroundings. But you could take it all the way back to how the electricity was generated in the first place.
30 paź 2024 · Energy is stored in objects. When a change happens within a system, energy is transferred between objects or between stores. The principle of conservation of energy states that: Energy cannot be created or destroyed, it can only be transferred from one store to another.
Key fact. Doing ‘work’ is the scientific way of saying that energy has been transferred. For example, a grazing cow, a firing catapult and a boiling kettle are all doing ‘work’, as energy is...
Energy can transfer between stores when a system changes. Examples. An object projected upwards: (e.g. ball thrown upwards): Kinetic store of ball → Gravitational potential store of ball. A moving object hitting an obstacle: (e.g. car hitting a traffic cone): Kinetic store of moving object → Kinetic store of obstacle.
Energy can be stored in one of many ways (like kinetic and gravitational potential) then transferred from one store to another by a number of processes including heating and radiation.
