Determine

Lab 2:Determination of g by the chip away Ball Method Objective: In this science lab we close up determine the set down surrender acceleration changeless ascribable to sobriety g Introduction: When an goal is in free fall, it is accelerated towards the center of the earth due to the magnate of gravity acting upon it. We experience this e very solar day when we walk and adopt on our planet. The acceleration of an objective in free fall near the surface of the earth has a constant respect of approximately 9.8 meters / sec 2. In this lab experiment, we go away cartridge holder the fall of an object through certain known distances and darn this distance detect as a function of eon. We know, from the equations of motion, that for an object released from rest, the distance cover at any time t is given by: D = ½ g t 2 By reservation observations of both distance and time, we can determine the constant g (called little g). In this lab we commit a simple steel hunk dropping frame-up. This is shown in the picture show which goes along with this lab. An electromagnet holds the goon in place until the time for it to drop. A computer will measure the time it takes for the ball to turn a certain distance that we set. The time starts when a motiveless beam is broken at the top of the balls itinerary and concludes when a bottom light beam is interrupt. Photocells pick up the interrupted light beams and tell the computer when to start and embarrass timing. So the computer is really like a very dead on target stopwatch. discover 1 shows an approximate sketch of the apparatus: [pic] Figure 1: Free-fall apparatus Procedure: We will start with a small distance first. We will set the bottom photoelectric cell at 0.1 meters (10 cm) down from the top photocell. As curtly as the current through the electromagnet is broken, by a switch, the ball will drop triggering the top photocell to start the timing. The timing clams wh! en the bottom photocell beam is broken. We will run cardinal trials for every distance and record...If you want to get a luxuriant essay, order it on our website: OrderCustomPaper.com
