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.

on the court with the Ford's off. My big dude, If God. So there is a dollar force on the open heart off magnitude F block because basically, this is upward force. This implies that a downward force on the opener should also be equal toe this cock. Now, we assume that there is no not talk on the opener so that it does not have any angular acceleration. So the next talk about the gym off the boat that the opener is resting on the gym should be equal to ay Alphand. Since there is no angular acceleration advice, you and so should be the next talk. Now, let's find that box of you have force f times 79 Mm minus. We have another talk on the opposite direction. So that is equal to if God guns my name. Um, this is a contra zero. From here we have f tow the equal. Nine over 79 dames have got GE now since the change off F cork beauties, some 200 new done 2 400 Newton Listen, is that if should also that he from lying over 79 things 200 Newton two lying over 79 dines 400 Milton. Involving this, we get the range of the magnitude off F B 22.8 Newtown. It comes from this. Ah, question. Do 45 0.6 meet them. So this is the range of F.
