This question is causing great confusion in my head.
Which of the following is an example of potential rather than kinetic energy? A) the muscle contractions of a person mowing grass
B) water rushing over Niagara Falls
C) light flashes emitted by a firefly
D) a molecule of glucose
E) the flight of an insect foraging for food
A) Muscle contractions is caused by the use of potential energy in ATP used by actin and myosin.
B) This is a classic example of what potential energy means.
C) Bioluminescence is a process caused by the use of chemical (potential) energy.
D) Yes, the molecule of glucose does contain potential energy. BUT, it is not potential energy itself...
E) Flight is kinetic energy. However, you can still boil this down to ATP in actin and myosin.
How do I approach this problem? My teacher said this is the type of problem she would give us. But this is so ambiguous. Am I lost?
