Environmental Engineering – study material
kinetic energy - correct answer ✔✔The energy of moving things
Potential Energy (PE) - correct answer ✔✔The energy an object has due to its
position
nuclear energy - correct answer ✔✔The energy released when atomic nuclei
split or fuse
thermal - correct answer ✔✔The energy of heat or temperature
radiant - correct answer ✔✔Energy transmitted via electromagnetic waves
Chemical - correct answer ✔✔energy stored in the bonds between atoms
Electrical - correct answer ✔✔The energy of flowing electrons
chemical energy - correct answer ✔✔A tank of gasoline on a motorcycle, a
partially charged cellphone battery, butter that dropped from a bagel, a scrap of
scorched paper
Nuclear energy - correct answer ✔✔high energy subatomic particles from a
radioactive element
, thermal energy - correct answer ✔✔An incandescent light bulb that burned out
moments ago, a pitcher of freshly brewed tea that was recently put in the
refrigerator, indeed-anything
kinetic energy - correct answer ✔✔A 3000 lb car rolling down the highway, the
needle moving toward your arm when you are about to donate blood, your
roommates sandals
potential energy - correct answer ✔✔A snap or clip on clothing, a mousetrap
ready for action, a paperclip gripping a stack of documents, pretty much anything
that could tip
electrical energy - correct answer ✔✔A bolt of lightening, the snap of static
when a sweater is removed in winter, that magic you expect to happen when you
flip a switch
Radiant energy - correct answer ✔✔The light of day, wireless connectivity at
the cafe, FM on the car radio, dental X-rays, the heat from a campfire.
Chose the answer that lists the electromagnetic wave radiant energy forms in
order, from longest wavelength to shortest, from lowest frequency to highest. -
correct answer ✔✔AM radio, microwave oven, heat from a person or pet,
incandescent light bulb, UV - black light, dental X rays, gamma rays from a
radioactive element
A ball of mass 2 kg is placed at a height of 50 m from the ground. If the ball starts
rolling down the inclined plane, what are the potential and kinetic energies at
positions A, B, C and D assuming that the ball does not experience any frictional
force? - correct answer ✔✔Let the ground be the reference for potential. Then,
