Use the simulation in your science or Physics class to illustrate elastic potential energy.
Simulation Summary: Elastic potential energy
Here is a concise summary you can use (e.g. for notes, a report, or to explain the simulation to someone else):
Summary of the Elastic Potential Energy Simulation
This interactive HTML/CSS animation demonstrates elastic potential energy stored in a stretched spring.
- Visual elements:
- A fixed wall on the left connected to a coiled spring.
- A colourful block (mass) attached to the right end of the spring.
- The spring stretches and contracts in a smooth repeating cycle (≈6 seconds per full oscillation).
- Key physics illustrated:
- Elastic potential energy (EPE) is stored when the spring is stretched.
- The formula is E = ½ k x² — energy increases with the square of the extension (x).
- When the extension is greatest (maximum stretch), the stored energy is highest.
- When the spring returns to its natural length, stored elastic energy drops to zero.
- Visual cues:
- An energy bar at the bottom fills up to maximum when the spring is most stretched and empties when relaxed — showing the quadratic (x²) relationship (doubling the stretch → 4× energy).
- Text reminder: “Greater extension → much higher stored energy (doubling stretch → ×4 energy)”.
- Educational focus:
- Highlights that elastic potential energy depends non-linearly on displacement (unlike kinetic energy’s v² relationship shown in a previous simulation).
- Useful for understanding energy transfers in oscillating systems (e.g. mass-spring, bungee jumping, trampolines, bow & arrow).
The simulation uses only HTML and CSS (no JavaScript) to create a smooth, infinite looping demonstration that clearly communicates the quadratic nature of stored elastic energy.
