The Physics of Skydiving

On thing that i would love to do in my life time is go skydiving. Fro what i understand there are three main parts to a skydive: free-fall, decent by parachute and touchdown. During free-fall, you re acceleration toward the earth at a rate of 9.81 meters per second per second. This just means that every second, you increase your velocity by 9.81 meters per second. However, due to air resistance, there is a maximum velocity that you reach because once you reach that velocity the drag force is equal to the force of gravity with causes a balance of force and therefor no acceleration. Second is the decent by parachute. When you first open your parachute, you slow way down because air resistance is greatly increased due to the parachute...which is its job. When the parachute is out, the rage force is equal to the force of gravity with allows you to fall at a constant speed. Then finally, touchdown. When landing back put earth, it would be smart to tuck and roll rather than just land. The reason for this is that if you do this you act sort of like a spring and don't take all the force at once but take it little by little. This will prevent injury and make your skydiving experience a lot more fun.
