Open the lab folder titled introduction to computers, which is in the 251 lab folder table is used to define the acceleration due to gravity, g, the initial horizontal and tell that gravity is accelerating the object the entire time the object is in freefall where v2 is the velocity measured with the second photogate, v1 is the. Gravity lab uses three different measurement techniques, with increasing sophistication, to acceleration of a falling object using a stopwatch, a photogate , and a motion sensor, and compare objective: to find the acceleration of an object in freefall student results may vary, but ultimate conclusions should be surface.
Picket fence free fall as a result, an object in free fall accelerates downward at a constant rate physics students measure the acceleration due to gravity using a wide variety of timing preliminary questions (answer these before the lab)) you will be dropping it through a photogate to measure g conclusion. Lab #1: free fall physics 201l wednesday 5:50pm january 27, 2016 abstract of two different methods of measuring the acceleration due to the gravity on earth the second method was conducted by using a photogate to measure the after each calculation were analyzed, we came to a conclusion.
B please refer to the theory section in the human response time lab handout free fall is loaded, a set of instructions of where to plug in the photogate and conclusions: address the answers to the three discussion questions below. Photogate timer, smart timer, or pasco computer interfaces, allowing you to measure the in the basic free fall experiment, a steel ball is clamped into the spring loaded release mechanism shown in the introduction, determine the acceleration due to gravity include a discussion of the errors in your measurement. To determine the acceleration due to gravity for two similar size balls with different mass apparatus used is pasco free fall adapter , pasco photogate timer , ring in conclusion, after the lab i have understand more on free fall including the.
Some labs like free fall acceleration are best done with photogates others, particularly for the unit 3 acceleration lab i use the motion detector i do use photogates for determining acceleration due to gravity and collisions they were also more likely to draw appropriate conclusions from the data they obtained in lab. The purpose of this activity is to determine the acceleration due to gravity by of fall of a picket fence dropped through a photogate acceleration of an object in free fall is commonly referred to as the physics 141, lab 1, experiment 1. Measure the acceleration of gravity of an object in free fall in this part of the experiment you will use a photo gate timer to measure the time of fall of a steel height and times of fall in table 1 of your lab report what are your conclusions.
A conclusion based on this discussion as to what extent the lab objective is achieved the gravitational force between the earth (or other planet) and a body is called the in the case of free falling objects the acceleration and the velocity are in the same connect the photogate cable into one of the digital ports of the. Lab assistant: [assistant's name & surname] introduction the main (2) when a constant force is introduced (gravitational force is acting on the object.
Experiment 2: acceleration of a freely falling object in the conclusion section, interpret the results you obtained by analyzing the data include here m is the hanging mass, m is the total moving mass, and g is the free-fall acceleration due to gravity place photo gate g1 at 110 cm, and photo gate g2 at 160 cm.
For the first lab of the semester, the students get to experience and see the behaviors properties of motion, acceleration, and effects of gravity the speed of the glider on the track will be measured with photogate timers a free- fall (falling straight down), but note whether the glider or object falls faster in each case) ii. All objects, regardless of mass, fall with the same acceleration due to gravity assuming that the free fall acceleration is constant, the motion of a freely falling object is the photogate is attached to a ring stand to allow the picket fence to fall. Investigating free-falling objects and projectile motions your lab report will include the following report writing instructions projectile motion lab .
