The laws of conservation are applicable in this technique because of the transfer of energy to other parts of the body. One should place their feet together, bend their knees, and tip over to a chosen side just as the ground is touched. Through this, the weight of the fall does not concentrate on the feet, rather it spreads throughout the body. Momentum gained during a fall depends on mass and velocity. The longer the time taken to land, the lesser the impact, and in consequence, bending knees is an effort to elongate the period of the force of impact. A longer period of impact scientifically means that the effects of the impact are transferred and reduced.
If a paratrooper or skydiver hits the ground with legs unfolded, he/she may break a bone or suffer worse injuries because of the sudden impact of force (Mei-Dan & Carmont, 2012). If the knees are bent, and one moves towards either side, the force of impact happens in a longer period, which is less deleterious to the person landing. In physics, the term conservation means that there is no loss in energy, only that it is transferred through objects without net change in the energy. It is necessary to roll as much as possible to ensure that the energy is tolerably transferred in the process of landing.
Apart from mild and serious injury, poor landing causes unnecessary embarrassment to a paratrooper or a skydiver. For this reason, there are diverse safety measure that skydivers and paratroopers must take to ensure successful landing. It is necessary to understand basic factors such as terrain, wind direction, an oscillation of the paratrooper or skydiver. These factors often vary and no matter the intensity of training given (Orlick, 2014), without proper information on natural factors, landing may be catastrophic. Injuries are common on the ankles, but necessary security measures must also be taken to protect the torso,
