Since of forces such as Air resistance. The plane’s

Since thebeginning of life, living things have been interacting with different kinds offorces every single day.

Force has existed even before the beginning of lifeand it is still and forever will be in this world, not only on the planet thatwe are living today but also in the entire universe. A force is a push and pullof an object caused by an interaction with another object. Force is measured inNewton and whenever two different objects interact with one and another, therewill always be a force acting upon them. When the interaction between two ormore object comes to an end, then those objects will not experience any kind offorce. My experience on riding an airplane several times can explain how forceswork. When the plane is moving in the air, it will be interacting withdifferent kinds of forces such as Air resistance. The plane’s speed is affectedby the air resistance which causes the plane to move slower than its originalvelocity. Air resistance also applied when a plane is landing on the runway.

The flaps that are located on the wings of the airplane raises causes a biggersurface for the air to be in contact with so that the plane can slow downfaster. The force of gravity is also one of the factors that the plane can landbecause the force keeps on dragging the plane down to the ground. ResearchQuestion:How willthe different surface area of the paper helicopter affect the time for thepaper helicopter to fall to the ground? Backgroundof StudyThe idea of force canbe explained by Isaac Newton’s Three Laws of Motion.

Isaac Newton was both amathematician and a physicist. He developed a few important things during histime such as the principles of modern physics also including the laws of motion.He’s famous work, which is the PhilosophiaeNaturalis Principia Mathematica, explains Newton laws of motion, which are:1.     First Law: “Every object persists in its statef rest and uniform motion in a straight line unless it is compelled to changethe at state by forces impressed on it.

” The main idea is that if there is no force is applied to the object, theobject will move at a constant velocity. If the velocity of the object is zero,then the object will stay put. If an external force is applied to the object,then the velocity of the object will change due to the force acting upon theobject. 2.       Second Law: “Force is equal to the change inmomentum (mV) per change in time. For a constant mass, force equals mass timesacceleration.”  This law explains how the speed of an objectbecomes different when it is applied by an external force.

It said that thechange of speed of an object is due to the mass of an object which means thatdifferent objects will have different velocity if it is applied to differentforces. The law also explains that force is equal to the change of momentum ofan object. 3.     Third Law: “For every action, there is anequal and opposite reaction.” The third law explains that every force thatexists in the world today, there will always an equal and opposite reaction.For Example, if Object A exerts 10N (Newton) of force on Object B, then objectB will do the same thing, which is also exerting 10N of force on Object A.  People used to imagineon how helicopters can fly and stay in the air.

Well, helicopters are able tofly and stay in the skies because of the spinning blades. Those “spinning blades”are capable of creating “lift”, which is a force that directly opposes theweight of an object and holds it up on the air. In helicopters and airplanes,the spinning blades are the ones who are creating the lift.

With enough amountof force, then a craft will be able to prevail over the force of gravity. PaperHelicopters or known as “whirlybird”, they don’t have motorized spinningblades, but they can create a few amounts of lift, which makes the paperhelicopter to fall down in a slower motion.  Hypothesis:-              Thelarger the surface area of the paper helicopter, the longer it will take thepaper helicopter to reach the ground. VariablesInvolved: –              IndependentVariable: Size of paper used-              DependentVariable: The time taken for the paper helicopter to reach the ground-              ControlledVariable: The same type of paper material that is use to build the paperhelicopter, height of the paper helicopter dropped, same material of paper clipused, same location that the experiment will take place, same number of paper clips,same kind of paper clips usedMaterialsand Apparatus-              Scissors-              Paper-              Paperclips-              StopwatchProcedure1.    Preparethe paper with the tracing of the Paper Helicopter and cut it by following theinstructions written.

2.    Aftercutting, process to folding the paper until the result of the folding is apaper helicopter. 3.

    Preparethe stopwatch to record the time for the paper helicopter to fall to the groundfrom a certain height. 4.    Dropthe paper helicopter from a certain height and measure the time it takes forthe paper helicopter to fall from the ground from that certain height. 5.    Recordthe measurements in the table6.

    Repeatthe investigation at least two more times, each repetition must use a biggerpaper helicopter in size. Safety/Risk-              Iwill show the teacher my investigation plan and ask permission before startingthe investigation.-              Iwill wear my laboratory coat whenever I’m carrying out the investigation-              Iwill report any kind of accident to the teacher immediatelyI will tidy up my work areaafter I finished my investigation
