The elastic potential energy stored in an elastic string or spring of natural length l and modulus of elasticityλ under an extension of x is given by: In solid mechanics, Youngs modulus (also known as the modulus of elasticity or elastic modulus) is a measure of the Stiffness of a given material. ...
This equation is often used in calculations of positions of mechanical equilibrium. A standard definition of mechanical equilibrium is: A system is in mechanical equilibrium when the sum of the forces, and torques, on each particle of the system is zero. ...
Elastic Potential Energy is the kind of energy that is stored in a bow, or in a catapult, or in a spring.
The energy stored = the work done to stretch the bow, so:
Elastic Energy (joules) = Average Force (newtons) x Distance (metres)
The factors that affect the amount of gravitational potentialenergy that is created are: the mass of the object, the distance that it is raised and the gravitational field strength.
Chemical energy is a form of potentialenergy related to the breaking and forming of chemical bonds.
A graph of a 1D or 2D potential function with the function value scale increasing upward is useful to visualize the potential field: a ball rolling to the lowest part corresponds to a mass or charge, etc. being attracted.
