Air resistance is the frictional force that an object has on air. Friction is resistance of an object’s surface. The amount of air resistance an object has is reflected on the speed of the object that has been dropped. Weight does not affect how fast an object falls. A plastic bag weighs about 5.5 grams. A piece of printer paper weighs about 4.5 grams. A handkerchief weighs about 3 ounces per square yard. Gravity drops all objects in the same was regardless of their mass or build structure (kidsdiscover.com). Gravity is the force pulling down an object that comes in the way. Acceleration is the change of speed or direction. The amount of mass something has is its weight which determines the amount of a downward gravity force it experiences. A falling object will continue to accelerate until air resistance force becomes more to balance the force that’s bringing the object (physicsclassroom.com). Isaac Newton’s 1st law of motion; an object has to stay in place unless it comes in contact with another object which causes force or a push for the objects to start to move. An object at rest stays in place unless a force is brought to it. 2nd law; force equals mass times acceleration (F=ma). 3rd law; every action has the same opposite reaction towards the first action. Generally increasing temperature lowers the density and viscosity, so it decreases the air resistance (Qoura.com). Handkerchiefs can be made out of any materials such as cotton, cotton-synthetic blend, synthetic fabric, silk or linen Ngonelo, Mxolisi. “Pocket Square vs Handkerchief vs Kerchief.” Perfect Gentleman, 1 Jan. 1970. Plastic bags are made from carbon which is used to make milk jugs, vinyl jackets and shopping bags Dumke, Mick, et al. “What Are Plastic Bags Made Out Of?” Chicago Reader, Chicago Reader, 10 Dec. 2017. They are usually made of colorless high-density polyethylene or low-density polyethylene (chicagoreader.com). Paper is mainly made from pulpwood logs and recycled paper products. Round parachutes have holes in them.The reason parachutes need holes when watching clothing hung crazy ahead An line ahead a windy day. A large sheet will make pushed upwards by wind.Light breeze make it go toward the center, looking like a parachute. When winds pick up, the sheet will begin should move all the more inconsistently. First the one corner, At that point the other, will flip outwards in the wind. This will make the sheet start twisting one way, then the another. The more harsh winds, the more the sheet will twist, In every corner thus flaps out to relieve the pressure from the wind. Whether air can’t undoubtedly move as it were that won’t aggravate those billowing shape parachute, it will rush out on one side, after that in turn this will make those parachute turn unpredictably, What’s more make it difficult for those parachute operator with control the jump. Assuming that the curving gets awful enough, those parachute will breakdown. The sides will flip up and the central bulge will snap closed like a fan, leaving the jumper in free fall with some string and loose fabric attached(gizmodo.com). Strings aso play a big role in parachutes. Longer strings cause the surface area to be bigger, which cause there to be more air resistance. Gravity is pulling on the object all the time, and with shorter strings gravity applies more force (prezi.com).
