MRCENT
Potential and Kinetic
Transformations
Energy Sources
100
Energy stored in the bonds on atoms, like batteries, gasoline, firewood, and food.
chemical energy
100
Stored energy that is ready to use
potential energy
100
Create an energy flow diagram with 3 forms of MRCENT:
A battery powered flashlight gives light.
chemical (battery) --> electrial (wires) --> radiant (light) --> thermal (heat is lost)
100
Explain the difference between renewable and nonrenewable energy
Renewable means the energy source won't run out and nonrenewable means we will eventually run out of it.
200
the faster the molecules in something move, the hotter its temperature
thermal energy
200
Energy in action or energy of motion
kinetic energy
200
Create an energy flow diagram with 3 forms of MRCENT:
Sunlight touches a solar panel and generates electricity and then some heat is lost.
radiant (sunlight) --> electrical --> thermal (heat is lost)
200
What energy source is burning plants, wood, or waste to release energy?
biomass
300
energy stored in the nucleus of an atom, it happens on the surface of the Sun when hydrogen atoms smash together (fusion)
nuclear energy
300
Explain where the most potential energy is
Point A because it is the highest and the roller coaster is not moving.
300
Mr. Ertekin started class by drinking 50 Joules (J) of coffee chemical energy which transformed into walking mechanical energy and sweating thermal energy. If he used 40 Joules of walking mechanical energy, how many Joules of sweating thermal energy was produced?
10 Joules. Because he started with 50 Joules so he must end with 50 Joules because of LOCEnergy (40 Joules + 10 Joules = 50 J)
300
Oil/petroleum, natural gas and coal are this type of non-renewable energy that is killing our planet through climate change
Fossil fuels
400
the energy an object has based on its motion or stored within by force (ex/compressed spring)
mechanical energy
400
Explain where is the MOST kinetic energy?
Point B because the roller coaster moves faster at the bottom of a ramp.
400
Create an energy flow diagram with 3 forms of MRCENT:
Ms. McCarthy lights a match and lights a candle.
chemical (match and wax) --> radiant (light) --> thermal (heat from fire)
400
Water in a dam travels down a tunnel and spins a turbine that produces electricity
hydropower / hydroelectric
500
the energy of waves, like light or microwaves
radiant energy
500
Which form(s) of MRCENT are potential energy? (2 possible answers- just give one)
Mechanical (if something is not moving) and chemical (energy STORED in the bonds of atoms)
500
What is the Law of Conservation of Energy?
Energy cannot be created or destroyed, it can only transform.
500
Explain geothermal energy and say if it's renewable or non-renewable
Geothermal energy comes from heat below the Earth's crust and it is renewable.
