What is this law called: energy can never be created or destroyed, only transferred or transformed
The Law of Conservation of Energy
Energy of motion/movement
What is kinetic energy?
Is thermal energy potential or kinetic?
Kinetic
What common metal in Earth's core causes Earth to have a magnetic field?
Iron
A route for electrons to flow
Circuit (will accept current as well)
What type of energy is almost always released during an energy transformation?
Thermal/heat
Potential energy stored in a body or material
What is chemical energy?
What are at least two units for measuring temperature?
Celsius, Fahrenheit, Kelvin
What is the negatively charged particle in an atom called?
Electron
What is a common energy source for a circuit?
Battery
Where does the energy in oil come from?
Dead plants and animals (which originally got their energy from other plants or animals or the sun)
On a roller coaster, what kind of energy is transferred to the rails and surrounding environment?
Thermal (from friction)
What is no thermal energy called?
Absolute zero
How does Earth's magnetic field help us?
Will accept: protects us from solar flares/the sun, helps us navigate using a compass, helps animals migrate
What are the three main components of a circuit?
Energy source, conductor, and energy receiver
Why is a flourescent bulb considered more efficient than an incandescent (regular) bulb?
It transforms the electrical energy into more light energy and less thermal energy
What is it called when the nucleus of an atom is split to harness energy?
Nuclear fission (will also accept nuclear energy)
