Potential Energy and Conservative Force#
A particle is acted on only by a conservative force. If the potential energy of this particle is zero at some point, then:
(Hint: draw a PE versus distance diagram–is there more than one way to satisfy PE = 0, and what does this mean about the conservative force?)
The net force on the particle is also zero.
The slope of the force versus position graph is zero at that point.
This does not allow us to determine the force at this point, nor the slope of the force versus position graph at this point.
The net force on the particle is positive.
The net force on the particle is negative.
