What is true about the energy in the system below?
a
the potential energy is lowest at point B because the distance between the swing and the earth is lowest at this point
b
the potential energy is greatest at points A and C because the farther the swing moves away from earth, the greater the potential energy is
c
potential energy is stored by an object because of its position relative to another object
d
as the child moves from point A to point B, kinetic energy is increasing
e
all these are true
f
all of these are false
