Kinetic Energy and Potential Energy(1)Kinetic Energy Energy can exist in many forms: heat, light, nuclear energy, chemical energy (from food or fuel), stored (potential) energy (such as the energy stored in a compressed spring) and so on. Energy can be transferred from one form to ...
A spring with a spring constant of 4 Newtons per meter is compressed by a force of 1.2 Newtons. What is the total elastic potential energy stored in this compressed spring? k = 4 N/m F = 1.2 N PE = ? Homework Equations PE = (1/2)(k)(x)^2 The Attempt at a Solution Using the...
A spring is a classic example of an elastic material. When a force is applied to a spring, it stretches or compresses, storing potential energy in the process. The amount of potential energy stored in a spring is directly proportional to the amount of force applied and the distance the ...

potential energy is energy stored in a system of forcefully interacting physical entities. The SI unit for measuring work and energy is the joule (symbol J). The term potential energy was introduced by the 19th century Scottish engineer and physicist William Rankine although it has ...
