Question

3.1415 6. As an object falls, it experiences an acceleration due to the force of gravity. The equation of motion for this object is: Where y is the instantaneous position of the object, t is the time that has elapsed, and g is the acceleration due to gravity. Using Excel, make a graph of the average vertical displacement vs t for the data in the table below. Draw a line of best fit and calculate the experimental value of gravity (g). After an experimental value has been calculated, use the known value of g 9.81 m/s2 to determine the percent error.

Explanation / Answer

If we plot graph between y and t, it would represent a parabola with its vertex at origin and focus on +y axis,

The slope of this graph at any time 't' would represent the magnitude of the speed of the falling object at that particular instance of time.
