Energy sources Flashcards
What is an energy
Energy is essential for every one of us. Humans have advanced because we have learned how to change energy from one form into another.
How many different forms of energy are there?
kinetic energy
heat energy
light energy
chemical energy
elastic potential energy or strain energy
gravitational potential energy
electrical energy
magnetic energy
nuclear energy
What is kinetic energy?
“Moving objects possess kinetic energy.
what is heat energy?
Heat is a form of energy that transfers from hot to cold objects.
what is light energy?
Light energy travels in waves and is a type of electromagnetic radiation.
What is chemical energy?
Chemical energy is a form of potential energy stored in the bonds of molecules.
what is elastic potential energy?
Elastic potential energy is the energy stored in an object as a result of its deformation, such as stretching or compressing a spring.
What is gravitational potential energy?
Gravitational potential energy is the energy an object has due to its position in a gravitational field.
What is nuclear energy?
Nuclear energy is a powerful source of electricity.
What is magnetic energy?
Magnetic energy can be harnessed and converted into electrical energy.
How can we measure energy?
To measure energy, we use a wattmeter device to measure energy in joules.
What is non-renewable energy?
Non-renewable energy sources are finite and will eventually run out.
Which things are non-renewable energy?
Non-renewable energy includes fossil fuels such as coal, oil, and natural gas.
