1 de mar. de 2011 · Jump velocity. (A) Histogram of the take-off velocities that ranged between 0.9 and 1.85 m s –1 in 51 jumps by 10 A. erinacei. (B) Projected distances that fleas would jump with a constant elevation of 39 deg. (i) Ratio of minimum and maximum distance predicted by fleas jumping with a constant elevation.

15 de sept. de 2009 · The hind legs propelled the flea to a take-off velocity of 1 m s –1 and to a measured and calculated height of 35 mm, or 23 times its body length. This is in the face of the considerable drag experienced on such a small body that reduces performance by 80% ( Bennet-Clark and Alder, 1979 ).
29 de jul. de 2013 · Both models correctly predicted the flea's take-off velocity, but then the Rothschild model began to go wrong. It predicted that the insect's acceleration peaked at a colossal 22,000m/s2 (2200g), whereas the acceleration of the fleas in the movies only peaked at 1500m/s2 (150g).
flea jumps only 20 cm (or so), but a leopard can leap about 2 meters. Why? Air resistance is part of the answer, as it relates to limitations to the F impulse. The acceleration of the flea to reach an initial velocity of 100 cm sec–1 is about 1.33 • 105 cm•sec–2 (the mass of the flea is about 0.45 mg)[2]. For man (or a leopard), the F ...
An energy dissipation at 1·12 ergs per leg or 2·24 ergs per flea is that calculated to produce a velocity of 1 m.sec −1 after 0·75 msec, in a flea weighing 0·45 mg. No allowance is made for energy loss due to friction.
