IntroductionSir Isaac Newton once said that for an object to move it must experience a force. This force will make the object move in a certain direction. When an object experiences a force it will move in the direction the force created until it experiences the opposite force which will cause it to stop. Newton later discovered that when objects move in a circular motion they want to move outward, away from the center, but they still go in a circle. He called this force that creates the above movement pattern Centripetal Force. This experiment shows how when we are in a car, on a roller coaster or on the swings at an amusement park, the centripetal force makes us move outwards and away from the center but also keeps us in circular motion. Investigative question Hypothesis What is the motion of an object during circular motion?VariablesIndependent variable: The speed at which the centripetal force generator is spun in one revolution. Example Kaelip vs. Jackie vs. Jean Claude's speed of revolution. (The variable changed by the experimenter)Dependent variable- The marble in the jelly (The appearance that is changed by the independent variable)Controlled variable- The consistency of the jelly.MethodMaterialsKettleMeasuring jugCold tap water3 packets of jellyStirring spoon5 plastic cupsPermanent markerFridgeMarblesScissorsRopeElectrical tapeInstructionsStep 1: to. Prepare the orange jelly according to the instructions on the box, but make sure to add more cold water than indicated on the box. In this case use 225 ml of hot water from the kettle and 340 ml of cold water from the tap.b. Once the gelatine has completely dissolved, pour the mixture into the 4 cups. By filling each cup... in the center of the card... the objects move when answered in a circular motion: they move outwards away from the center. Cup number 4 didn't work in my experiment because the jelly was too soft and the marble sank to the bottom. I would improve my experiment by thickening the jelly for cup 4. Cup 3 the marble did not move, this could be a result of the jelly being too hard. I can improve this purchase by making sure to add more cold water next time. The above information about gelatin miscalculations would be the error in my experiment. Objects move outward when centripetal force is applied.
