Lab Report TITLE: Using a pendulum to find gravity Aim: To find the gravity by finding the period of the oscillations of a pendulum and plotting a graph. Hypothesis and Prediction: - the gravity from the graph is going to equal the gravity from the formula. Variables: The independent variable is the length of the string The Dependent variable is the period of one oscillation Controlled variables are: - mass of the pendulum Equipment: -Brass Ball -string -boss and clamp -stopwatch -2 metal blocks -Meter Ruler -Micrometer -The diameter of the brass ball was measured using a micrometer. Then the value was divided by 2 to give the radius -the length of the string was measured -two metal block were clamped with the string in between, the string was tied to the bob -the bob was pulled to the side and released -the time was started when the bob passed the reference line. -a full oscillation is when the bob passes the reference line forth back and forth again. - the length of...
