Elastic Potential Energy Formula:
| From: | To: |
Elastic potential energy is the energy stored in elastic materials as a result of their stretching or compressing. It is the energy that can be recovered when the object returns to its original shape.
The calculator uses the elastic potential energy formula:
Where:
Explanation: The formula shows that elastic potential energy is proportional to the square of the displacement and directly proportional to the spring constant.
Details: Calculating elastic potential energy is crucial in physics and engineering for understanding spring systems, designing mechanical devices, analyzing oscillatory motion, and solving conservation of energy problems.
Tips: Enter spring constant in N/m and displacement in meters. Both values must be positive numbers. The calculator will compute the elastic potential energy in Joules.
Q1: What is the spring constant (k)?
A: The spring constant measures the stiffness of a spring. A higher k value indicates a stiffer spring that requires more force to stretch or compress.
Q2: Why is the displacement squared in the formula?
A: The displacement is squared because the work done in stretching/compressing a spring increases quadratically with displacement, not linearly.
Q3: What are typical units for this calculation?
A: Spring constant in N/m, displacement in m, and energy in Joules (J). 1 Joule = 1 Newton-meter.
Q4: Does this formula apply to all elastic materials?
A: This formula specifically applies to ideal springs that obey Hooke's Law. For non-linear elastic materials, more complex formulas are needed.
Q5: What is the relationship between force and elastic potential energy?
A: The force required to stretch/compress a spring is F = kx, while the energy stored is U = ½kx². The energy represents the work done to deform the spring.
