What are the types of forms of energy |
Electrical, lights, kinetic, sound, heat, there is also potential energy including gravitational chemical, elastic and nuclear |
|
|
What are the three types of heat transfer |
Convection, conduction, radiation, |
|
|
Explain the law of energy conservation |
Law of energy conservation is that energy cannot be created nor destroyed energy transfer his energy being passed from one object to another for example kicking a ball |
|
|
Explain electrical energy |
electrical energy is produced by power stations, solar cells, batteries and lighting. Electrical energy Powers your TV, phone, microwave and toaster. |
|
|
Explain kinetic energy |
Kinetic energy is the energy of movement. Anything that move moves has kinetic energy. The faster an object moves, the more kinetic energy it has |
|
|
Explain heat energy |
he energy can come from the sun, flames, chemical reactions, electrical devices are even from a personal animal. It warms, Burns, dries, milk, and makes hot air balloons rise |
|
|
Explain light energy |
light energy comes from the sun, light globes, fires and animals such as glow worms. Without light energy, the world would be a very dark place. |
|
|
Explain sound energy |
Sound energy is the energy that air has when it is vibrating. Your ears and brain interpret the vibrating of air is sounds. Sounds comes from your voice, musical instruments, cars and power tools. |
|
|
Explain stored energy |
Stored energy is another name for potential energy, 4 examples of potential energy include gravitational potential energy, chemical energy, elastic potential energy, and nuclear energy |
|
|
Explain gravitational potential energy |
gravitational potential energy is energy stored in object is above the ground. The greater the height of an object the more gravitational potential energy it has. For example, the hire a water slide, the more gravitational potential energy you have at the top and more the more kinetic energy you will have on the way down! |
|
|
Explain chemical energy |
chemical energy stored in substances. Energy is released by your body when you digest food, and buy cars on fuel is burnt. Wood, paper, apples, petrol and batteries all contain chemical energy. |
|
|
Explain elastic potential energy |
elastic potential energy stored in a in a stretched or squashed spring stretched rubber bands also store elastic potential energy which is released when they're let go |
|
|
Explain nuclear energy |
nuclear energy is stored inside the tiny Adam's that make up all matter nuclear energy is released in nuclear power plant when a nuclear bomb explodes comma and inside the sun. Nuclear reactions produce heat and light. |
|
|
Explain energy transfer |
energy can be passed from one over another this is known as energy transfer for example when you kick a ball kinetic energy from your foot is transferred to the ball causing the ball to move. |
|
|
Explain heat transfer |
kinetic energy is not the only type of energy that can be transferred when you standard front of a heater, you energy is transferred from the heater to you, warming you up. He added you can catch on speaker transferred and three ways conduction, convection, radiation. |
|
|
Explain conduction |
conduction happens between two objects that are in contact he transfers from the hotter object into the cooler one until they are both the same temperature |
|
|
Explain convection energy |
you don't need to touch a heater in a room to feel heat transfer this is because he can flow through liquids and gases this process is called convection it is confection that causes heat to rise making it harder near the ceiling then down on the floor |
|
|
Explain radiation |
heat radiates from any hot object this type of heat transfers called radiation radiant heat is transferred as a wave that can travel even through the vacuum of space |
|
|
Energy transformation |
energy can be transferred from one object to another. And if you can also be changed, or transformed, from one type of energy into another type of energy. Whenever you watch TV, listen to music or play on a games console you are relying on energy transformation iPads TVs and phone's convert electrical energy into sounds, light and heat energy. This is shown through an energy flow diagram |
|
|
Explain how to calculate energy efficiency |
To calculate energy efficiency you divide the useful energy output bite the total energy input and then you times that by 100 |
|
|
Explain efficient housing and three examples |
efficient housing is an energy efficient house that that makes it easier for households to reduce energy use. It is estimated that about half of the energy costs of running a house it's keep it warm in winter and cool in summer. Examples of these things include floor insulation, LED lighting, north facing windows, native vegetation ect |
