Elastic Potential Energy Equation:
From: | To: |
The elastic potential energy equation calculates the energy stored in an elastic object when it is stretched or compressed. It is commonly used for springs and other elastic materials that obey Hooke's Law.
The calculator uses the elastic potential energy equation:
Where:
Explanation: The equation shows that the energy stored in a spring is proportional to the square of its displacement and directly proportional to its spring constant.
Details: Calculating elastic potential energy is essential in physics and engineering for designing springs, shock absorbers, and various mechanical systems that store and release energy.
Tips: Enter spring constant in N/m and displacement in meters. Both values must be positive numbers greater than zero.
Q1: What is the spring constant?
A: The spring constant (k) measures the stiffness of a spring. A higher value indicates a stiffer spring that requires more force to stretch or compress.
Q2: What are typical units for elastic potential energy?
A: Elastic potential energy is measured in Joules (J) in the SI system, which is equivalent to Newton-meters (N·m).
Q3: Does this equation apply to all elastic materials?
A: This equation applies specifically to ideal springs that obey Hooke's Law, where force is proportional to displacement. Some materials may have non-linear behavior.
Q4: What happens if the displacement is doubled?
A: Since energy is proportional to the square of displacement, doubling the displacement quadruples the elastic potential energy stored.
Q5: Can this calculator be used for compression and extension?
A: Yes, the equation works for both compression and extension as long as the displacement is measured from the equilibrium position.
