I always have wondered how the military men used skydiving to intrude behind enemy lines and conduct various missions. After doing a bit of research I found out that Military skydivers are deployed from a large aircraft or at times from a helicopter in order to do their respective jobs which are mostly in the form of missions. They carry more gear then the normal skydivers, aside from the parachute they carry additional equipment’s like oxygen tank, weapons and other equipment’s which are needed for their missions so this becomes more challenging for these daredevils. So factors like mass of the skydiver, equipment they carry and the surface area  or height by which they fall from will affect the speed at which the travel. It would be hence interesting to design an experiment to see how these factors affect the terminal velocity of a parachute.Terminal Velocity occurs during free fall  when a falling body experiences zero acceleration that is when there is no acceleration in the parachute. It varies directly with the ratio of drag to weight. Terminal velocity reaches when the force of gravity  acting on the object is equal to the air resistance or viscous force of air on the body. Air resistance  is a major factor contributing in a falling object to reach terminal velocity as it can easily contribute to the speed at which the body falls.
