Another related equation gives the mass ratio in terms of the end velocity \ Delta v relative to the rest frame ( i . e . the frame of the rocket before the acceleration phase ):
12.
In other words, the second 100 metres is run with a " flying start ", without the slow acceleration phase of the first 100 metres and without the greater than 0.10 s reaction time of the start.
13.
Current knowledge of coronal mass ejection kinematics indicates that the ejection starts with an initial pre-acceleration phase characterized by a slow rising motion, followed by a period of rapid acceleration away from the Sun until a near-constant velocity is reached.
14.
If your model was correct, then driving at a constant speed on a level highway with no turns would only require gasoline during the acceleration phase, and you could turn the engine off and cruise for the rest of the trip.
15.
During the brief mass acceleration phase of each cycle, the engine s physical action is like that of other reaction engines & mdash; gas mass is accelerated rearward, resulting in an application of force forward into the body of the engine.
16.
Svalbard surges are typically associated with slower onset with an acceleration phase, rising to a maximum velocity which is typically slower ( up to four or five meters per day ) than Alaskan surges, and a return to quiessence often taking years.
17.
The inverted wing is even equipped with a large aileron, such that the driver can adjust the generated downforce in such a way that the vehicle achieves high traction during the acceleration phase and low drag ( i . e . low downforce ) during the high-speed phase of the race.
