Freefall and Projectile Motion

Free croak and missile exertion Introduction and Objectives This lab experiment was through to determine the characteristics of free slip by and skyrocket communicate in Physics. The motion in which a body is thrown or projected is called projectile motion while free fall is any motion of a body where gravity is the only force acting upon it, at least initially. In this experiment, a photogate, a chopper, and a Universal Lab embrasure were utilise to determine the free fall motion of the chopper as it was released.A ball, carbon paper, and an L-shape projector were as well as used to determine the range of projectile motion of a ball being released from a horizontal except slightly vertical slope. At the end of the experiment, sensation forget recognize how velocity and period affect the acceleration of a free fall object and its projectile motion. Thoery Aristotle stated in his theory of motion that the fall of a heavy object toward the center of the earth is a grap hic motion because the object is just returning to its natural place.He also stated that heavy objects fall faster than lighter ones because increase in the rate of motion is proportional to the weight of the object. Galileos theory states that the when a ball was rolled down an inclined plane at placed angle? the ratio of the distance covered to the square of the corresponding sequence was always the same, further that when the angle of inclination is changed, the perpetual also changes but remains the same for the same angle. The constant d/t2 is also the constant for falling object (refers to the acceleration due to gravity).The experimental range used in the experiment is 45 cm, and the expression of the range of the projectile was prepare in terms of Vg and h. The horizontal distance traveled by the projectile for the total term of flight is given simply by R=vxt where t is the total time of flight and vx is the constant horizontal velocity. The time of flight was found using the equation for vertical motion, which is y=yi + viyt-1/2gt2. by and by each experiment, the Logger Pro software determined the curve of the time vs velocity graph to determine which had a better Linear fit, each the Quadratic or the Linear curve. http//physicse-book8. blogspot. com/) Results and Discussion A.

I t was shown that under the influence of gravity, an object go on its own with its velocity accelerating at a constant pace. It is express that when the only force acting on an object is the Earths gravitational force,it is in free fall. There cannot be any different force acting upon it, especially air resistance, which should either be remove or ignored by its minute size.The force of gravity on an object is nearly constant when the object in free fall is near the earths surface. Because of this, the object accelerates downward at a constant rate. This acceleration is usually represented with the symbol g. In this experiment, a precise timer was connected to the computer and a Photogate was used to greenback the acceleration due to gravity. The Photogate has a beam of infrared light that travels from one side to the other. It can detect whenever this beam is blocked. A Picket make do or a chopper, a piece of clear plastic with equally spread out black sections on it, was dr opped. As the Picket moot spelles through the Photogate, the computer will measure the time from the leading coast of one bar blocking the beam until the leading edge of the adjoining bar blocks the beam. This timing continues as all eight bars pass through the Photogate. From these measured times, the program will calculate the velocities and accelerations for this motion and graphs will be plotted. http//www. waukeshasouth. com/physics1/photo. html http//www. oppapers. com/essays/Picket-Fence-Free-Fall/567967
