Determining the effect of the mass on the drop time of a parachute Introduction and hypothesis The drop time of a parachute is dependent on multiple factors. Apart from mass, there is the obvious height, area of the parachute and other external factors such as wind. Mass is one of the main effectors of the drop time of a parachute, which can be proven through Newton’s second law, F=ma (Force=mass*acceleration). Rearranged, this gives a=F/m, where acceleration can also be gravity, if falling down…

an aerodynamic force which acts parallel and opposite to the motion of the object when it moves through a fluid. It is caused by friction and differences in air pressure. There are many factors can affect the magnitude of drag force as with aircraft lift. The drag depends linearly on the shape and size of the object moving through the air. The object’s cross-sectional shape determines the form drag which is created by the pressure variation around the object and affects the induced drag of the…

compressed such that the object may pass with ease. If it is non-compressible the air drag will increase thus denying the object maneuverability. Factors Affecting Lift: Object: Similar to drag, the objects shape and size all affect the lift. Obviously, mass is inversely proportional and surface area is directly proportional. Motion: Lift is dependent of the velocity of the fluid and how the object is inclined to…

First, how planes fly needs to be understood. Airplanes fly because the wings cause lift. The lift of the wing has to be greater than the amount of gravity that is pulling down on the plane. The wings cause lift because of an airfoil shape. The wings are rounded on the top and almost flat on the bottom. The air has to go farther over the top of the wing so there is a low pressure area above the wing. This causes the lift of the wing and holds the airplane in flight.…

distance usually stays in the air for a long time because they have a lot of lift but little thrust, but they are meant to be thrown with a lot of force. Unlike paper airplanes, darts don’t have a lot of lift nor drag because they depend on extra thrust to overcome gravity. Also another way balance can affect the plane's flight is by having different weight on opposite sides. For instance, more weight on the back with have more lift but will land sooner than having more weight in the front.…

Fig.\ref{Str_1_T} compares the jet trajectory measurement for the open nozzle configuration at the two blower velocities. Fig.\ref{Str_1_W} compares the weight distribution along the centerline axis, normalized with respect to the total mass distributed. Fig.\ref{Profiles_1}.a shows the centerline profile of the straw distribution on the ground, normalized to their respective maximum weights and Fig.\ref{Profiles_1}.b shows the jet spreading along curvilinear trajectory $\zeta$.…

the coefficient of lift, pressure drag and pitching moment. Variations of these parameters with incidence and flap deflection were investigated. Thin aerofoil theoretical prediction of a 2π/radian lift curve, aerodynamic hysteresis and theoretical aerodynamic centre at 0.25C were examined. 1 Introduction The experiment investigates the characteristics of an aerofoil in a 2D incompressible viscous…

strenuous place to reach but you can have a little fun too, but if you can’t roll with the punches it can be exhausting if you’re new to snowboarding. Mammoth has copious amount of activities for people of all skill levels and age groups, like kids ski club for the little ones. All the way up to double black diamond slopes for pros. There are also bars, cafes, a small museum of sorts, and shops for people who like to shop on their vacation. The whole trip was a little exhausting; still it’s…

Growing up in Vail, I would often ride the chair lift with strangers and they would ask, “Where are you from?” I would reply “here.” The people I shared the chairlift with would tell me how lucky I was, but I would just smile politely and nod, unaware of my fortune. I had grown up in mountains and didn’t know anything different. As I have gotten older and been fortunate enough to have traveled outside of my familiar mountain range, I have realized how intensely beautiful mountains are. Now that…

investigate to find out. If you do not stop once in awhile, you will never see that opportunity that faces you. My last ski run of the day gave me opportunity to see beauty in the world and showed me that I have someone watching over me. The snow is falling and the clouds cover the sky in grey as if there was a forest fire on the other side of the mountain. The…
