Description

Gravitational acceleration by using the Simple Pendulum:


You will turn in Data table 3, P44, and Post-lab questions # 4 and 5. Try to be brief and on target. You should support your answers with formulas whenever possible.
Also, you will need to plot a graph either on graph paper, or on Excel for length versus period squared. Multiply the slope from the graph by 4 π2 to find g.

Equation g= 4 π2 ( L/T2)

Compare average g from the table and g from the graph to the accepted value for g and find the % error.


You need to show the calculations for the following steps:

T(period) by dividing the total time in seconds on the number of swings

g, by using pi, length of string in meters and the period squared in seconds squared as shown in the above equation.

Find the percent errors as explained above

Gravitational acceleration by using the Simple Pendulum

Summary:
By using T=2π√L/g as formula, we will be able to find out the
theoretical values for different angles.
Period of the object= Starting Time + The Final Time
But each time we let the Pendulum go, it will come up at the
same place. By paying attention with the air%, this is reason why
it could came back at the same place.

Introduction:
In thus experiment, Students will be able to study the small angle
approximation, the period depends on mass and length.
However, with the formulae, we find out the slope of the ending
graph which helps us to determine and understand on a diffe...
