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:
