100
The ability to cause change.
What is energy?
100
Cleaner energy, but fish habitat can be negatively affected by dams.
What is hydroelectricity?
100
Used to generate wind energy.
What kinetic or mechanical energy?
100
Measures distance or height.
What is the meter?
100
The work done when a 2.5-kilogram book is pushed with a force of 40 Newtons a distance of 5 meters.
What is 200 joules?
200
Type of energy stored in a rubber band when it is stretched out.
What is elastic potential energy?
200
Clean, quiet, and plenty of supply, but very inefficient and expensive.
What is solar energy?
200
Geothermal energy that uses hot spots.
What is thermal energy?
200
Measures mass.
What is kilogram?
200
The gravitational potential energy of a lamp with a mass of 4kg on shelf 2.5m high.
What is 98 joules?
300
Energy of motion.
What is kinetic energy?
300
By-product is water, but can be explosive and requires energy to make energy.
What is hydrogen fuel?
300
Used to create Hydroelectricity.
What is kinetic or mechanical energy?
300
Represents speed, or a simplified version of velocity without direction.
What is meters per second (m/s)?
300
The kinetic energy of a 62kg adult swinging 2 m/s.
What is 124 joules?
400
Form of energy that travels through vibrations in gas, liquid, or solid.
What is sound energy?
400
VERY efficient, but creates dangerous radioactive waste.
What is nuclear power?
400
Power that takes advantage of the fact that uranium atoms are highly radioactive and break down by fission.
What is nuclear energy?
400
Represents both work and energy.
What is joule?
400
The mechanical energy of a 34kg child going 4 m/s down a water slide with 272 J of kinetic energy and 9.3 J of potential energy.
What is 281.3 joules?
500
States that no matter how energy is transferred or transformed, all of the energy is still present in one form or another.
What is the law of conservation of energy?
500
Renewable energy, but less efficient than fossil fuels, and still pollutes the air when burned.
What is biomass?
500
Converted when fossil fuels and biomass are burned.
What is chemical energy?
500
Measures force.
What is Newton?
500
The gravitational potential energy of a 33-pound (15 kg) TV sitting on a shelf 100cm high.
What is 147 joules?
