How does energy move from hot to cold objects?
|
Conduction (when heat is transferred through or between solids.The heat is passed on by vibrations in the molecules)
|
|
|
Name active energys
|
Thermal/heat, Light, Kinetic, Sound, Electric
|
|
|
Name Potential energys
|
Gravitational, Elastic, Chemical
|
|
|
What does the term mean by Gravitational potential energy
|
Gravitational potential energy is energy an object possesses because of its position in a gravitational field.
|
|
|
What does the term by kinetic energy
|
Kinetic energy is the energy which a body possesses because of its motion
|
|
|
What is the law of conservation of energy
|
Energy can never be created or can never be destroyed, but can change form
|
|
|
What is the unit for energy
|
The joule
|
|
|
What is the unit for power
|
watt
|
|
|
what is the definition of conduction
|
When heat is transferred through or between solids. The heat is passed on by vibrations get bigger.
|
|
|
what is the definition of convection
|
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat
|
|
|
What is the definition for Radiation |
Radiation is energy transmitted in waves or a stream of particles. The first thing you think of as radiation is probably X-rays, but what cooks your food in the microwave oven is also radiation.
|
|
|
What is the difference bettween heat and temperature |
Heat is an energy and temperature is a measurement of how hot an object is |
|
|
What is climate change brief explanation |
When the world is heating up from fossil fuels |
|
|
What are the different methods of generating energy |
Geothermal, Solar panels, Wind turbines, Hydro electricity |
|
|
What is geothermal energy |
Geothermal energy is the heat from the Earth. It's clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.
|
|
|
What are solar panels |
a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.
|
|
|
What is hydro electricity |
Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water.
|
|
|
What are wind turbines |
This is done by using a large wind turbine usually consisting of propellers; the turbine can be connected to a generator to generate electricity, or the wind used as mechanical power to perform tasks such as pumping water or grinding grain. As the wind passes the turbines it moves the blades, which spins the shaft.
