In physics, potential energy is the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. The unit for energy in the International System of Units is the joule (J). One joule can be defined as the work required to produce one newton of force, or one newton times one metre. Potential energy is the energy of an object. It is the energy by virtue of an object's position relative to other objects. Potential energy is associated with restoring forces such as a spring or the force of gravity. The action of stretching the spring or lifting the mass is performed by a force which works against the force field of the potential. The potential energy of an object is the energy it possesses due to its position relative to other objects. It is said to be stored in the field. For example, a book lying on a table has a large amount of potential energy (it is said to be at a high potential energy) relative to the ground, which has a much lower potential energy. The book will gain potential energy if it is lifted off the table and held above the ground. The same book has less potential energy when on the ground than it did while on the table. If the book is dropped from a height, it gains kinetic energy, but loses a larger amount of potential energy, as it is now at a lower potential energy than before it was dropped.

you know that this would be the diagram of the system and we know the table. It's the metrics of the person Consider near either EJ and the same distance will result. We know that this system has static equilibrium and we can say that this sum of torques would be equaling zero. This would be equal to M G. This would be multiplied by point 60 meters and then this would be minus on G X. This would be equaling to zero and so X is going to be equaling 0.60 meters multiplied by M over the larger mass m. And so this would be equaling 0.60 meters lower case Them, of course, is the mass of the table, 24.0 kilograms divided by the mass of the person, 66.0 kilograms and we find that ax is equaling 0.218 meters now. Then the distance from the edge of the table would equal 0.50 meters minus point 218 meters and this is gonna be equaling point two 82 meters. This would be our final answer. The distance from the edges of the table. That is the end of the solution. Thank you for watching
