Jan 1, 2010 · Power ratings are given to appliances to show the amount of energy transferred per unit time. Common power ratings are shown in the table below: Power Ratings Table. Power and power ratings are useful because power describes how fast the energy is transferred from one store to another.
Revision for AQA Physics GCSE, including summary notes, exam questions by topic and videos for each module.
A system is an object or group of objects. When a system changes, the way energy is stored also changes. Examples: Ball rolling and hitting a wall. System is moving ball. When it hits the wall, (some of) the kinetic energy is transferred as sound. Vehicle slowing down. System is vehicle moving.
Jan 1, 2013 · The vibrating particles transfer energy from their kinetic store to the kinetic store of neighbouring particles. The direction of energy transfer is always from hot to cold. The higher the thermal conductivity of a material, the higher the rate of energy transfer by conduction across the material.
