PLEASE DO BOTH LABS FOR THUMBS UP

A freely falling ruler Related concepts: constant acceleration, falling due to gravity You will need: a centimeter ruler, a thin strip of paper (12 inches long. 1/2 inch wide) tape, a friend to drop your ruler Description: The purpose of this experiment is to show the distances traveled by a freel;y falling object (in the absence of air resistance), to measure your reaction time, and to introduce acceleration in terms of g's Activity: By definition of a freely falling body, gravity is the only force acting on ift Suppose an object is held suspended at rest and is then released. After t seconds have passed, the object has fallen a distance d (in meters) given by d = ½.gt. where g is the acceleration due to gravity, g = 9.8 m/s Fill out the table saying how far an object will fall in 0.05 second, 0.10 second, 0.15 second, 0.20 second, and 0.25 second. Convert your values for d from meters to centimeters. (The first answer is given so you can check yourself.) Tape a narrow strip of paper down the middle of your ruler. Mark a line at one end of the ruler (at 0 cm), and mark other lines at the distances in your table (at 1.2 cm, etc). Label each line with the time it would take for the ruler to fall that far Measure your reaction time (in intervals of 0.05 second) by trying to catch the ruler when a friend drops it between your fingers (with no advance warning), starting with your fingers at the 0 cm mark..

Explanation / Answer

Now the table as per equation can be given as formula using d = 1/2 g t2

Now the expirement values are noted below here, we can see that this is much closer to equation

Distance Time 12.25 cm 0.05 49 cm 0.1 110.25 cm 0.15 196 cm 0.2 306.25 cm 0.25
