What can you conclude about every during the time that Jillian is winding the spring and
during the times that the car is slowing to stop on the carpet? -CORRECTANSWER
When Jillian winds the spring, energy is not being created, but instead is just being
transferred from her to the car; and when the car is slowing down to a stop, energy is
not being lost to friction, but instead is just being transferred from the car to the carpet
and other things.
A ball is thrown straight up into the air. As it rises after leaving the hand, what is the
relationship between the gravitational potential energy and the kinetic energy of the
ball? -CORRECTANSWER The total energy remains constant, so as the kinetic energy
decreases, the gravitational potential energy increases by the same amount.
Suppose during a certain period of time the dry battery decreases in chemical potential
energy by 300 joules. During that same period of time, what happens to the thermal
energy in the surroundings? -CORRECTANSWER It increases by less than 300 joules.
For the same situation described above, suppose during that same time period the dry
cell battery transfers 250 joules of energy to the buzzer. Assume the buzzer has an
efficiency of 60%. How much energy does the buzzer transfer to the surroundings to
, increase their thermal energy during the same period? -CORRECTANSWER 100
Joules
Contact Push/Pull (CPP) -CORRECTANSWER Objects in contact push or pull on each
other
Heat Conduction (HC) -CORRECTANSWER Objects in contact have different
temperatures
Infrared Radiations (IR) -CORRECTANSWER Non-touching objects have different
temperatures
Convection (Con) -CORRECTANSWER Fluid (liquid or gas) flows between non-
touching objects with different temperatures.
Heat Interactions (HI) -CORRECTANSWER A collective name used when at least two
of the HC, IR, and Con are occurring between objects at the same time.
Electric circuit (EC) -CORRECTANSWER An electrical energy source is connected to
an electrical device in a circuit.
Light -CORRECTANSWER Light moves from a source to a light receiver
