Potential Energy - Example 7.5-1
Can the gravitational potential energy
V
g
= mgh
be negative?
Yes
No
What is the potential energy of the particle at positions 1, 2 and 3?
V
g1
= mg*
V
g2
= mg*
V
g3
= mg*
What if we change the location of our datum? Now what is the potential energy of the particle at positions 1, 2 and 3?
V
g1
= mg*
V
g2
= mg*
V
g3
= mg*
