The difference between elastic potential energy compared with kinetic energy or gravitational potential energy is that when you start stretching an elastic band or a spring, it is really easy to extend it, but the more you stretch the harder it becomes and the more force you need to exert on it (assuming you never break or deform it). Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing. KE = 1/2mv^2 (note KE is kinetic energy) You could rearrange for v as the subject 2KE = mv^2 v^2 = 2KE/m v = (2KE/m)^1/2 also you would not include plus or minus because a negative velocity makes no sense.

In the equation above, "P.E" is the elastic potential energy and expressed in joules, "X" is the displacement and "K" is the spring constant. What are the names of Santa's 12 reindeers? For Enquiry. The knowledge of potential energy of a system at a point is a useful result, but what we ultimately want is an equation that predicts the position of a particle at any moment of time, along with its energy. 2) A spring with a spring constant k = 800 N/m has been compressed, and 196 J of potential energy is stored. The formula for measuring potential difference is V=W/Q and this formula is known as Ohm's law. The gravitational influence on a body at infinity is zero, therefore, potential energy is zero, which is called a reference point. There is a deep connection between force and potential energy. Solving for the Elastic Potential Energy / Energy stored inside the spring: a. Click to see full answer. The rate or spring constant, k, relates the force to the extension in SI units: N/m or kg/s2. Is elastic potential energy always positive? Potential energy is energy that is stored in a system, based on the position of objects. Watch out for units, remember in the end to work in J, m and kg. Springs have their own natural spring constants that define how stiff they are. Kinetic Energy: Kinetic energy is the energy associated with an object's motion.
