Energy

1.Joule, unit of work or energy in the International System of Units (SI). Named in honour of the English physicist James Prescott Joule.

2.Kinetic- the energy of an object that is due to the objects motion Potential- the energy that an object has because of its shape, position, or condition of the object. Mechanical- the amount of work an object can do because of the objects kinetic and potential energy. Thermal- all of the kinetic energy due to random motion of the particles that make-up an object. Chemical- energy of a compound that charges as its atoms are rearranged Electrical-the energy of moving electrons Sound- when a vibrating object transmits energy through the air around it Light- produced by the vibrations of electricity charged particles Nuclear- the energy that comes from changes in the nucleus of an atom

3.I can say what kind of energy is produced when I am given a picture of a name of an object. For example a radio produces sound energy. A fire produces heat energy. Most houses are powered by nuclear energy A lightbulb produces light energy

4.Identifying input energy is when you put energy in an object. You are powering something e.g. when a torch is powered it is powered by the chemical energy so the chemical energy is the input energy. Also when you are kicking a ball you are using kinetic energy to kick it so the kinetic energy is the input energy. When you plug a plug into a socket, the socket is holding some electrically energy. When you plug the plug in the socket the electrical energy is going in to a device so the electrical energy from the socket is the input energy.

6.Seeing a lightbulb turn on you can identify that it electrical energy to light and heat. Another example is solar panels: it has light energy going in and electrical/chemical energy coming out

9. A Sankey diagram shows the energy transfers in an object like a light bulb or a phone the thicker line shows the more energy it uses. A Sankey diagram has two arrows one going down to show the wasted energy and the other arrow going straight to show the useful energy.

10.Something consumed to produce energy: a. A material such as wood, coal, gas, or oil burned to produce heat or power. b. Fissionable material used in a nuclear reactor. c. Nutritive material that you eat, food.

11.Fossil Fuels are formed by the remains from animals and plants. Coal, oil and natural gases.

12.Crude oil, coal and gas are fossil fuels. They were formed over millions of years, from the remains of dead organisms. coal was formed from dead plant material. crude oil and gas were formed from dead marine organisms.

14.There many products of combustion, most of which are gases. Two of these are carbon dioxide and sulphur dioxide
