PHYSICS when a positive charge moves under the influence of an electric field's electrostatice force, what happens to the electrical potential energy of that charge?

If the E-field pushes the charge, the electrical potential energy of the charge decreases.

When a positive charge moves under the influence of an electric field's electrostatic force, the electrical potential energy of that charge changes. Electrical potential energy is the energy associated with the position of a charged object in an electric field.

The electrical potential energy of a positive charge increases when it moves further away from a positively charged object, or closer to a negatively charged object. Conversely, the electrical potential energy decreases when the positive charge moves closer to a positively charged object, or further away from a negatively charged object.

To calculate the change in electrical potential energy, you can use the formula:

ΔPE = q * ΔV

Where ΔPE is the change in electrical potential energy, q is the charge of the object, and ΔV is the change in electric potential (also called voltage) experienced by the charge.

By multiplying the charge (q) by the change in voltage (ΔV), you can determine the change in electrical potential energy.

It's essential to note that the electric potential energy is a relative quantity, meaning it is defined with respect to a reference point. Typically, the reference point is chosen to be at an infinite distance from all charged objects, where the electric potential is considered zero.
