how does potential decreases when there there is force of attraction between a positive charge and a negative charge
When a force acts on an object, it can cause a decrease in the object's potential energy. This is because the force does work on the object, transferring energy from the object's potential energy to its kinetic energy.
Potential energy is the energy that an object possesses due to its position or state. It is stored energy that can be converted into other forms, such as kinetic energy, when the object is acted upon by a force.
Potential energy and force are directly related. When there is a force acting on an object, it can change the object's potential energy by doing work on it. This can either increase or decrease the object's potential energy, depending on the direction of the force.
The formula for potential energy is P.E. = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object. This formula applies to objects located near the surface of the Earth.
Yes, potential energy can be negative. This occurs when the object's position is below the reference point, usually the ground or a set height. Negative potential energy means that the object has less potential energy than it would at the reference point.
