?
The Attempt at a Solution
i think its twice the work
Potential energy is the energy that an object possesses due to its position or state. It is stored energy that can later be converted into other forms of energy, such as kinetic energy.
Potential energy is calculated by multiplying the object's mass, the acceleration due to gravity, and the height or distance the object is from the ground. The formula for potential energy is PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height or distance.
Potential energy and kinetic energy are both forms of energy and are interrelated. As an object gains potential energy, it loses kinetic energy, and vice versa. This is known as the law of conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another.
The conservation of energy applies to potential energy through the principle of conservation of mechanical energy. This principle states that the total amount of mechanical energy, which includes both potential and kinetic energy, remains constant in a closed system. This means that energy can be transferred between potential and kinetic energy, but the total amount remains the same.
Some examples of potential energy include a stretched rubber band, a compressed spring, and a book on a shelf. When a stretched rubber band is released, it converts its potential energy into kinetic energy as it snaps back to its original shape. A compressed spring converts its potential energy into kinetic energy when it is released. A book on a shelf has potential energy due to its position, and if it falls, it converts its potential energy into kinetic energy as it moves towards the ground.
