mfb said:If you go down in potential energy, you lose energy. Therefore, the force should point towards points of lower potential. The direction of electric field is the force for positive charges (convention), therefore you have to take the negative derivative of the potential to get the electric field.
The potential energy depends on the charge of the object.
Potential is a property of a system that describes its ability to do work, while potential energy is a measure of the energy stored in a system due to its position or configuration.
The higher the potential of a system, the greater the potential energy stored within it. This means that the more work the system is capable of doing, the more energy it has.
Potential energy can be converted into other forms of energy, such as kinetic energy, thermal energy, or chemical energy, through the process of work. When work is done on a system, its potential energy decreases and is converted into another form of energy.
Yes, potential energy can be negative. This typically occurs when the reference point for potential energy is chosen to be at a higher energy level than the system's natural state. In this case, the potential energy of the system is negative because it requires work to bring it back to its natural state.
Gravitational potential is a type of potential energy that is determined by the position of an object in a gravitational field. As an object moves further away from the source of the gravitational field, its gravitational potential energy increases. This is because the object has to do work against the gravitational force to move away from the source.
