It isn't clear what you mean by "it". In the case of gravitational potential energy, it is greatest when an object is at its highest position (or when two objects are furthest apart). For other types of potential energy, the situation is different.
it is most likely that yes, everything has potential energy.
It can be described in several ways, but elastic potential energy is the most useful.
Yes. Chemical potential energy. When you light it most (nothing is 100% efficient) of the potential energy is converted to kinetic energy.
There are several types of potential energy, not just 3. The following are probably the most important ones:Gravitational potential energy, i.e., the potential energy in a gravitational field;The potential energy in an electric field;The potential energy in a magnetic field;Elastic energy;Chemical energy;Nuclear energy.
He would have most potential energy when he hasn't started going down yet, since the higher he is, the greater his potential energy. Potential Energy= mass*gravity*height(from ground)
Most of the kinetic energy will have turned into potential energy - all of it, if there is no friction.Most of the kinetic energy will have turned into potential energy - all of it, if there is no friction.Most of the kinetic energy will have turned into potential energy - all of it, if there is no friction.Most of the kinetic energy will have turned into potential energy - all of it, if there is no friction.
The higher it is located, the more potential energy it has.
The ball has the most potential energy at the highest point of its trajectory
Potential energy is the amount of energy stored in an object due to its height. This is maximum for an object which has maximum height and vice versa. So the most potential energy would be for object with greatest height.
gravitational energy
Potential energy is a form of energy that is stored within an object and it can be released or converted into another form of energy. Potential energy is most often associated with restoring forces such as in a spring, which stores potential energy when compressed or stretched.
If you were talking about gravitational potential energy, assuming each ball was at the same height, the one with the most potential energy would be whichever is heaviest. If each ball weighs the same, whichever one is highest up has more potential energy.
