Study Notes

Gravitational potential energy is stored energy that gravity can convert into kinetic energy, which can then be converted into hydroelectric power for various uses.
Electric potential energy is energy stored by electric charges and is essential in designing circuits for electrical power.
Electric potential energy depends on the type and amount of charge as well as the strength of the electric field, measured in Joules.
A calculation example is given to determine the electric potential energy stored by a charge based on specific values and distances.
Electric potential energy is the ability of a charge to do work, with the positive or negative sign indicating whether work must be done to keep charges apart.
Electric potential energy decreases as it is converted into kinetic energy, following the law of conservation of energy.
Electric potential energy resembles gravitational potential energy in terms of dependence on position in a field and the ability to be positive or negative.
Electric potential, measured in volts, is the electric potential energy per unit charge and is different from electric potential energy, which represents the energy of all charges in a system.
The electric potential at a point in space depends on the amount of charge creating the potential and the distance from that charge, expressed in an equation involving Coulomb's Constant (k), charge (q), and distance (r).
The total electric potential at a point due to multiple charges is the sum of the potentials from each individual charge at that point, calculated by adding the potentials from each charge separately.
