Physics of Skydiving :: physics skydiving

The Forces at WorkGravity... God OBVIOUSLY intended for us to skydive. After all He DID give rise gravitational attractionSo scarcely what runs are acting on the skydiver? Well, of course theres the obvious one, the force of solemness of the Earth. This force is exerted 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 deuce targets exert forces on one another even though they are not touching, is known as a noncontact force.According to Newtons second law, the acceleration of an tendency as produced by a net force is promptly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the intention 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 the 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 come out of the closet is a constant 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 quantitative measure of inertia, where inertia is the natural tendency of an object to tour of duty at rest or in motion at a constant fastness along a straight line. var. oppositionAnother force acting on the parachutist is station resistance. Air resistance is the colliding of an object with molecules of send out. 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 rise up 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 work it does on an object moving in between two points depends on the path of the motion between the two points. The amount 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.
