Physics of Skydiving :: physics skydiving

The Forces at WorkGravity... God OBVIOUSLY intended for us to skydive. later all He DID create gravitySo exactly what military capabilitys ar acting on the skydiver? Well, of course on that points the obvious one, the coerce of gravity of the Earth. This force is doed on everything on the Earth and is exerted on the skydiver even though there is no direct contact between the skydiver and the Earth. This type of force, when two endeavors exert forces on one a nonher even though they are not touching, is known as a noncontact force.According to Newtons second law, the quickening of an object as produced by a clear force is directly relative to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object orFnet =maThe gravitational force that the Earth exerts on the skydiver is equal to the weight of the object on Earth. The acceleration of the gravitational force is the acceleration due to gravity (g), which is t he acceleration of an object under the sole influence of gravity. Thus, the weight of an object is a product of its mass and acceleration due to gravity orW=mgThe acceleration due to gravity (g) near the Earths surface is a eonian that was determined to be 9.80 m/s. So, the weight of an object depends on how much mass an object has. The mass of an object is a vicenary measure of inertia, where inertia is the natural tendency of an object to stay at rest or in motion at a constant speed along a straight line.Air Resistance some other force acting on the parachutist is air shield. Air electrical tube is the colliding of an object with molecules of air. The falling skydiver collides with air molecules during the downward fall. These air molecules create a force pushing upward which is opposite to the skydivers direction, as well as the force of gravity. Air Resistance is more complicated force than the force of gravity because it is a nonconservative force. A nonconservative force is one in which the realise it does on an object moving in between two points depends on the path of the motion between the two points. The tote up of air resistance encountered by the skydiver depends mainly on two factors1 The speed of the skydiver.2 The cross-sectional area of the skydiver.An increase in the speed and/or the amount of cross-sectional area leads to an increase in the amount of air resistance encountered.
