Physics- Electricity and energy. 0.0 / 5 ? FunFunNone Created by: emuppetCreated on: 18-05-14 10:27 What are the eight types of energy? Remember, sleckteg! Sound, light, electrical, chemical, kinetic, thermal, elastic and gravitational . 1 of 25 What's sound energy? Anything noisy gives off sound energy. 2 of 25 Light energy? Anything luminous gives off light energy. 3 of 25 Electrical energy? wherever there's a current flowing, there's electrical energy. It's easily converted into other forms. 4 of 25 Chemical energy? Anything with stored energy which can be released by a chemical reaction. 5 of 25 Kinetic energy? Anything that moves has kinetic energy. 6 of 25 Thermal energy? Anything with a temperature above absolute zero(-273 degrees) has heat energy. The hotter something is, the more heat energy it has. 7 of 25 Elastic energy? Anything stretched has elastic energy. 8 of 25 Gravitational potential energy? Anything above the ground has potential energy. e.g anything that can fall like ski jumpers and planes. 9 of 25 What is a series circuit? The components are connected to each other in one loop. 10 of 25 What's a parallel circuit? The components are connected in branches. 11 of 25 True or false: The current is always the same in a series circuit. True. 12 of 25 True or false: The current is used up in a circuit. False. 13 of 25 Why do thin wires have low resistance? Because not as many electrons can flow through them. 14 of 25 A small current in a circuit makes bulbs... dim. 15 of 25 Which type of wire will have the most resistance: long or short? Long because the current has further to travel. 16 of 25 What component can be used to reduce the current in a circuit? A resister. 17 of 25 What happens when more bulbs are added in a parallel circuit? The resistance get smaller, so the current gets bigger. 18 of 25 What do we measure current in? Amps. 19 of 25 What's a short circuit? A short cut for the current. 20 of 25 Why would a current prefer to go through a wire than a bulb? The wire gives much less resistance to the flow. 21 of 25 Heat is transferred only if there's a... temperature difference. 22 of 25 Where does most of the energy come from? The sun. 23 of 25 What type of energy resources will run out? Non- renewable energy resources such as fossil fuels. 24 of 25 What type of energy resources won't run out? Renewable energy resources such as wind power, biomass and solar power. 25 of 25
