The purpose of the Picket Fence Free Fall Lab was to examine the acceleration of objects as they fall to earth. During free-fall the only force that should be acting upon the object is the earth’s gravitational pull (9.8 m/s/s)‚ therefore the velocity of the object should always equal 9.8 m/s/s. In this lab the picket fence was dropped repeatedly through a photogate connected to Logger Pro‚ which allowed the fence’s acceleration and velocity to be recorded and graphed. The results of the experiment

Introduction The Disbursement Acceleration Program of the Aquino Administration should not be implemented because it does not contribute in the GDP and economic growth of the country‚ although it may have been partially successful‚ its rediscovery has drawn reaction as “Unlawful”‚ aside from being unconstitutional‚ it does not serve‚ neither its spending was translated to over-all increase of jobs‚ nor trigger a downturn in poverty incidence. II. Background The Disbursement Acceleration Program (DAP) is a

They do not fit. They come in from the outside‚ they are suggested patterns‚ some dull and some of great beauty.” Free Fall; Sammy Mountjoy; pg. 2 Free Fall is not a mere story of a man’s “fall”‚ but a consuming story of search‚ existence‚ choice and self-realization. It is a story of an artist‚ an artist

Acceleration Worksheet 3 Worked Example A cheetah running at 20 m s−1 slows down as it approaches a stream. Within 3.0s‚ its speed has reduced to 2 m s−1. Calculate the average acceleration of the cheetah. Solve the following: 1. A sports car‚ accelerating from rest‚ was timed over 400 m and was found to reach a speed of 120 km h−1 in 18.0 s. a. What was the average speed of the car in m s−1? b. Calculate the average acceleration of the car in km h−1 s−1. c. What was

Fate and Free Will The idea about free will and fate is still unsolved and debatable throughout the world. Some claim that humans have their own power to create their own destiny‚ however‚ others argue that they are inescapable victims of fate. The novel‚ Things Fall Apart‚ portrays the relationship between human’s determination to succeed and his or her own fate by describing Okonkwo as a tragic figure. While Okonkwo believes that he can overcome his fate through his hard work‚ Chinua Achebe

experiment is to measure acceleration on a freely falling object assuming the only force acting on the object is gravitational force. Theory All dense objects in free fall have the same acceleration‚ which is known as the acceleration due to gravity. The value of acceleration due to gravity is approximately 9.80 m/s2. In this experiment‚ a vertical stand with an electromagnet at the top for holding and then releasing of the falling body‚ called the plummet. The plummet falls between two vertical

Lab Conclusion When comparing the average speed results from part two of the lab and the definition of acceleration‚ you find similarities between the two. First‚ average speed is distance divided by time‚ and we use it to describe the motion of an object moving at changing speeds. We can see this from our lab results from the average speed of the marble traveling down the ramp‚ because it picks up speed. When the marble is released at the top of the ramp‚ the ball doesn’t have the same momentum
