1. What is Elastic Potential Energy to Kinetic Energy Conversion?

Elastic potential energy to kinetic energy conversion describes the transformation of stored energy in a spring (elastic potential energy) into motion energy (kinetic energy) according to the principle of conservation of energy.

2. How Does the Calculator Work?

The calculator uses the energy conservation equation:

\[ \frac{1}{2} k x^2 = \frac{1}{2} m v^2 \]

Where:

\( k \) — Spring constant (N/m)
\( x \) — Displacement from equilibrium (m)
\( m \) — Mass of the object (kg)
\( v \) — Velocity of the object (m/s)

Explanation: The equation shows that the elastic potential energy stored in a spring is converted entirely into kinetic energy of the attached mass when released.

3. Importance of Energy Conservation

Details: The principle of conservation of energy is fundamental in physics, stating that energy cannot be created or destroyed, only transformed from one form to another. This calculator demonstrates this principle in action.

4. Using the Calculator

Tips: Enter the spring constant in N/m, displacement in meters, and mass in kilograms. All values must be positive numbers. The calculator will compute the resulting velocity.

5. Frequently Asked Questions (FAQ)

Q1: What assumptions does this calculation make?
A: This calculation assumes an ideal spring that follows Hooke's law, no energy losses to friction or air resistance, and that all elastic potential energy is converted to kinetic energy.

Q2: Can this be used for compression springs as well as extension springs?
A: Yes, the equation works for both compression and extension springs as long as the displacement is measured from the equilibrium position.

Q3: What if there are energy losses in the system?
A: In real systems with energy losses, the actual velocity will be less than calculated. This calculator provides the theoretical maximum velocity.

Q4: Does this work for springs with non-linear behavior?
A: No, this equation assumes a linear spring that follows Hooke's law (F = -kx). For non-linear springs, more complex calculations are needed.

Q5: What are typical units for these measurements?
A: Spring constant is typically in N/m, displacement in meters, mass in kilograms, and velocity in meters per second.
