If a group of point charges as a whole, has positive potential energy, what does that mean? What will happen if the point charges are free to move?

Will it? The total PE of the system will bejonathan.15 said:Yes I am referring to electric potential energy of a group of point charges, say 2 negative and 1 positive. This group of charges will have a net negative potential energy.
As for what it means to say that the system has a net negative potential energy, please see my previous reply.jonathan.15 said:What does this mean? What will happen?
Positive U refers to the positive or upward direction on a graph or coordinate system. It is typically associated with the y-axis, or vertical axis, on a Cartesian plane. In physics, positive U can represent a change in position or displacement in the upward direction.
No, positive U and positive slope are not the same. Positive slope refers to the direction and steepness of a line on a graph, while positive U refers to the direction of displacement. A line with a positive slope may not necessarily have a positive U displacement.
Positive U is typically calculated by measuring the change in position or displacement in the upward direction. This can be done by measuring the vertical distance on a graph or calculating the difference in y-coordinates.
The opposite of positive U is negative U, which refers to the negative or downward direction on a graph or coordinate system. In physics, negative U can represent a change in position or displacement in the downward direction.
Yes, positive U can be seen in real life in many situations. For example, when an object is thrown upwards, it experiences a positive U displacement. In addition, a graph of an object's height over time would show a positive slope, indicating a positive U velocity.
