- Q1What is the science word for how energy changestransformationtranspirationconvection300s6.9c
- Q2The Law of Conservation of Energy says
There is more energy in the universe than before
Energy cannot be created or destroyed, it only changesEnergy always transforms into matter
300s6.9c - Q3
Energy Loss means
Some energy is released as thermal energy during any energy transformation
The amount of energy in the universe is decreasing.
Some energy is destroyed whenever energy transforms
300s6.9c - Q4
A force that always creates thermal energy and slows things down is
Friction
Nuclear
Gravity
300s6.9c - Q5
The name for a machine that is supposed to be able to run forever is
a perpetual motion machine
a free energy machine
a constant velocity machine
300s6.9c - Q6
Perpetual motion machines can never really run forever because of
friction
dark matter
kinetic energy
