Initial velocity

Also found in: Medical, Acronyms, Encyclopedia.
the velocity of a moving body at starting; especially, the velocity of a projectile as it leaves the mouth of a firearm from which it is discharged.

"I have looked at the question in all its bearings, I have resolutely attacked it, and by incontrovertible calculations I find that a projectile endowed with an initial velocity of 12,000 yards per second, and aimed at the moon, must necessarily reach it.
At any NADPH concentration where the GSSG-dependent substrate inhibition is observed, increasing the initial concentration of GSSG in the reaction mixture resulted in a decrease in both the initial velocity and the relative amplitude of the first stage, concomitant with a significant rise in the duration of the inhibited stage.
These values helped to plot a graph representing the angle of entry according to the angle of throw [alpha], graphically represented in parallel with the one describing the initial velocity required by [alpha] for a more intuitive analysis.
According to current breakup theories, both the Saito model and the IKEMIX code model assert that L/D ratio varies with Froude number, that is, related to the initial velocity. Epstein's correlation, however, suggests that L/D varies with the density ratio of the jet and surrounding fluid without the influence of velocity.
When [gamma] [greater than or equal to] 2, no matter how much the initial velocity difference is, the minimum weighted intervehicle distance will always be 13 m.
[DELTA][v.sub.A,n+1], [DELTA][[epsilon].sub.Axn+1], and [DELTA][[epsilon].sub.Ayn+1] are the deformation increments at the n + 1th time step of block A, [V.sub.0] = [0 [V.sub.1,n] 0 [V.sub.2,n] [V.sub.3,n] 0] and [A.sub.0] = [0 [A.sub.1,n] 0 [A.sub.2,n] [A.sub.3,n] 0] are the initial velocity and initial acceleration at the n + 1th time step of block A, [v.sub.M,n] and [v.sub.N,n] are the accumulated displacement at points M and N, and [[sigma].sub.Ax,n] and [[sigma].sub.Ay,n] are the stress components at the nth time step.
One of these three damaged projectiles with the initial velocity of 356 m/s got the most serious damage and all the empennages were broken, but the shape of projectile stayed intact.
In this experiment, the four participants followed a circular experimental turning course where the initial velocity was 64 km/h at the beginning of the 40 m radius turn, and where 0.2 G of braking begins in 35 s (Figure 11).
For drop jumps, maximum height (in cm), initial velocity (in m/s), and jump angle (in radians) were measured for each jump, while for wedge jumps only initial velocity and maximum height were measured, as jump angle should be controlled largely by the angle of the wedge (Spagna et ah, 2009), which was static.
Initial velocity of the pulse is taken to be zero; in that case the pulse splits into two bell-shaped pulses with half of the initial amplitude and propagating in opposite directions.
