This calculator divides stored energy by an entered release interval. A separate animation shows a generic spring-charge, latch and release sequence without predicting jump performance.

Equation Used
- Entered energy is released over the entered interval.
- The physical animation shows slow charge, latched hold and rapid release but is not dimensioned.
- No mass, gravity response, spring rate, losses, force, stroke or motion law.
The animated spring, latch and payload illustrate a release sequence. Timing and travel are assigned for display and do not change with the entered energy or interval. Peak power requires a time-dependent power trace.
Slow charge, latch and rapid release
Spring-powered jumping mechanisms commonly use a low-power input to store elastic energy, a latch to hold the charged state, and a trigger for rapid release. The diagram shows a guided payload touching the spring through charge and expansion, a fixed-height latch that closes over the compressed payload, and a separate illustrative flight phase after contact ends. This is a simplified sharp-contact-latch sequence, consistent with the mass–spring–latch arrangement in Divi et al., Latch-based control of energy output in spring actuated systems, figure 1. The charging actuator and automatic return hardware are omitted. Neither the displayed motion law nor the cycle timing is a dynamic prediction.
The calculator reports only E/Delta t. Its inputs do not determine the animated travel or trajectory.
Use as a unit check
The arithmetic can compare stored energy and release-interval scenarios. It cannot size the spring or latch or predict jump height, speed, force, landing or stability.
Average power
Pavg=E/Delta t. Instantaneous power can be above or below this average. Its maximum is the peak power, which cannot be determined from the average alone.
Interpretation
60 J over 100 ms averages 600 W. That result does not specify payload acceleration, takeoff speed or height.
Limitations
Energy and release time determine interval-average power only. Predicting motion also requires mass, the spring force through its travel, losses and release behavior. The illustration omits charging and return hardware, and its eight-second display cycle is independent of the release-time input.
Questions
Is this peak power?
No. It is interval-average power.
Is the animated jump height calculated?
No. It is an illustrative phase marker only.
