If the time is t, the landing velocity is V, and the impact force is f. It can be calculated by the formula ft = MV
objects that fall only under the action of gravity without any resistance are called & quot; Free fall & quot;. An object, such as one that begins to fall from a static state under the action of the earth's gravity. The sky near the earth's surface can be regarded as a constant gravitational field. If the atmospheric resistance is not taken into account, the motion of the free falling body in this region is uniformly accelerated linear motion. Its acceleration is equal to the acceleration of gravity G
extended data:
the main characteristics of free falling body
the characteristics of free falling body motion are reflected in the word "free", which means that the object is stationary when it begins to fall, that is, the initial velocity v = 0. If the initial velocity of the object is not zero, even if it falls vertically, it cannot be regarded as a free falling body
(2) in the process of falling, the object is not affected by any other external forces (including air resistance) except gravity, and the resultant force of external forces is 0
(3) the falling time of any object is the same when it falls freely at the same heightsource of reference:

there are many unsuccessful currencies in history, such as the Deutschmark in the Weimar Republic and, more recently, the Zimbabwean dollar. Although previous currency failures were usually e to over inflation that could not happen on bitcoin, there were always potential technical errors, currency competition and political problems. The basic lesson is that no currency can be considered absolutely safe from failure or difficult times. Bitcoin has been proven reliable for several years since its birth, and it has great potential to continue to grow. But no one can predict the future of bitcoin< The rapid rise in price of BR />
does not constitute a bubble. Artificial overestimation will lead to a sudden downward revision, which will form a bubble. The price fluctuation of bitcoin caused by the indivial behavior of thousands of market participants is the result of the market determining the price. From the emotional point of view, the reasons for price changes include: the loss of confidence in bitcoin, the huge difference between price and value not based on the fundamentals of bitcoin economy, more and more news reports stimulating speculative demand, fear of uncertainty, and outdated irrational prosperity and greed.
