Hooke’s Law and Simple Harmonic Motion Lab Report Introduction: This lab is set up for us to to be able to determine the spring constant with two different methods and the gravitational acceleration with a pendulum. The spring constant refers to how “stiff” a spring is. Springs are elastic meaning that once they are stretched or compressed they are able to return to their original state. Springs tend to have a higher spring constant, and once they are deformed they are a great example of Newton’s Third Law of Motion stating that for every force there is an equal opposite force. This elastic behavior of springs can be explained through Hooke’s Law and formula [1]. Objective: Within the experiment, in the first two parts we will determine the spring constant of a spring using two different methods. In the third part of the experiment we will determine acceleration due to gravity by using a simple pendulum. Hooke’s Law helps explain the first parts of this experiment. Hooke’s Law states that if a force (F), is applied to the opposite end of a material holed on, parallel to the length, then in general the material is either compressed or stretched by distance (x) .The relationship of this can be best explained through the equation: F = -kx [1] Where k is kept as a constant. In this experiment since the material used will be a spring then the constant k will be called a spring constant. In the third/last part of the lab, we are to determine acceleration due to gravity with a pendulum. Stated by theory the total time period of a pendulum can be calculated through the following equation T = 2π √ l/g [2] l

G = 4π2(l/T)

Slope= 0.6904

costant k = 57.18 % diff= 9.91 % New Section 11 Page 1

Percentage difference= 9.9% Conclusion= My tests both showed that the spring obey the Hooke’s Law. That means that I have completely reach my aim as found out that the laces obey Hooke’s Law. Percentage difference is 9.9 % which is quite acceptable. Possible reasons for the errors could be due to temperature and air changes which could lead to the change in Force constant. We could use thermometer to avoid this error....
