Table 2 Comparison of the jumping performance of Phidippus regius against Sitticus pubescens19, and Phidippus princeps20. All three jumps are level jumps.
From: Energy and time optimal trajectories in exploratory jumps of the spider Phidippus regius
Species | Reported jump gap, R (mm) | Body mass, m (mg) | Take-off velocity, v (m/sec) | Time to take-off, t (ms) | Take-off angle, θ (deg.) | Acceleration, a (m/sec2) [a = v/t] | g-force, g-f [g-f = a/9.81] | Kinetic Energy, KE (μJ) [KE = 0.5mv2] | Jumping Power, P (mW) [P=KE/t] | Specific Power, SP (W/kg), [P/m] |
|---|---|---|---|---|---|---|---|---|---|---|
Sitticus pubescens | ~50 | 10 | 0.67 | 13.06 | 12 | 51.30 | 5.23 | 2.24 | 0.17 | 17.19 |
