How it works
Biological Formula Standard
Elastic potential energy is the energy stored in a deformed elastic material such as a spring, rubber band, or bow. For an ideal spring obeying Hooke's Law (F = kx), the stored energy equals ½kx². This energy can be fully recovered as kinetic energy when the spring is released, making it a conservative form of energy. The quadratic dependence on displacement means doubling the stretch quadruples the stored energy.
Frequently Asked Questions
What is the spring constant k?
The spring constant (k) measures a spring's stiffness in Newtons per meter (N/m). A higher k means a stiffer spring that requires more force to stretch. It depends on the spring material, wire diameter, and coil geometry.
Does compression or extension store the same energy?
Yes, for an ideal spring the energy stored is the same whether compressed or extended by the same distance x. The formula U = ½kx² depends only on the magnitude of displacement, not its direction.
Where is elastic PE used in real life?
Elastic potential energy is used in mechanical watches (mainspring), archery (bow), trampolines, car suspensions, and many engineering applications where energy needs to be stored and released.
