Measurement of Free-Fall Acceleration Introduction Galileo Galilei (1564-1642)‚ the man first accredited with the correct notion of free-fall with uniform acceleration‚ stated that ’if one were to remove entirely the resistance of the medium‚ all materials would descend with equal speed.’ Today‚ this statement holds true for all objects in free-fall near the Earth’s surface. The purpose of this experiment is to verify Galileo’s assertion that acceleration is constant. In addition‚ the magnitude

Abstract In this experiment Newton’s Second Law of Motion was measured with the use of the gravitational acceleration g on Earth by applying a free fall process. Objective The objective of this experiment is to validate Newton’s Second Law of motion. In experimenting the Law the measurement of acceleration of gravity was used by measuring the distance a dropped ball travels for a specific amount of time. Procedure First‚ measurements were taken of the distance from the stairway

The effect of distance between dominoes and time taken to fall Introduction By collecting data whilst keeping all variables constant apart from the independent and dependent variables of an experiment‚ it is possible to determine a relationship between them. One relationship that can be observed in a laboratory is the relationship between the distance (denoted by symbol d) of separation of dominoes in a domino chain and the time taken (denoted by symbol t) for all dominoes to fall over. It is expected

Sample Formal Laboratory Report for Physics on the Picket Fence Lab (CP) without the parachute Purpose: The purpose of this experiment is to verify the acceleration due to gravity using the picket fence with a photogate‚ LabPro and LoggerPro software by measuring it with a precision of 0.5% or better. Theory: All objects‚ regardless of mass‚ fall with the same acceleration due to gravity assuming that there is no air resistance. Objects thrown upward or downward and those released from

earlier to determine the identity of different substances. To determine the precision of your technique‚ you will calculate the percent error‚ which is a comparison of the differences between the measured value and accepted value. Percent error can be determined as follows: % Error = (Measured Value – Accepted Value( x 100 Accepted Value OBJECTIVES When you have completed this activity‚ you should be able to: Observe the chemical and physical properties of substances

Lab {4} Free Fall Motion Abstract Within this laboratory students used a Macintosh computer‚ scientificwork interface‚ and photogate to measure the acceleration of gravity‚ g‚ in a free-fall experiment. Using a “picket fence” dropped through a photo gate with disregard for air resistance; students calculated the results from the charted data and compared it with the accepted value of 9.8 m/s2 discussing any variations and their
