The potential of pure water (Ψ w pure H 2 O) is, by convenience of definition, designated a value of zero (even though pure water contains plenty of potential energy, that energy is ignored). Water potential values for the water in a plant root, stem, or leaf are therefore expressed relative to Ψ w pure H 2 O . Therefore, water moves constantly in direction of potential energy (i.e. wet to dry soil), where the gradient of potential energy with distance is the moving force causing flow. An indication of the tendency of soil water to move is expressed by the soil water potential ( Ψ ).

Potential energy is often associated with restoring forces such as a spring or the force of gravity. The action of stretching a spring or lifting a mass is performed by an external force that works against the force field of the potential.

The equation for calculating the potential energy of a spring is PE = 1/2 * k * x 2, where k is the spring constant and x is the amount of compression.

An indication of the tendency of soil water to move is expressed by the soil water potential ( Ψ ). The total energy of the universe is a constant; if the system loses energy, it must be gained by the surroundings, and vice versa Internal Energy (E) The sum of all kinetic and potential energies of all components of the system

Plants use water potential to transport water to the leaves so that photosynthesis can take place. Water potential is a measure of the potential energy in water as well as the difference between the potential in a given water sample and pure water. Water potential is represented by the equation Ψ system = Ψ total = Ψ s + Ψ p + Ψ g + Ψ m. Elastic potential energy is defined as the energy possessed by virtue of stresses within its body and electric potential is defined as the energy possessed by an object by virtue of the total charge stored within. Potential Energy Formula. The formula for gravitational potential energy is given below. That unifying principle is the concept of water potential. All of these can be related by the general equation for water potential for plants and soils. Water potential is defined by its chemical activity or free energy. Bound water has less chemical activity or free energy than free water and therefore has a negative water potential.
