What is the purpose of the simple pendulum experiment?
The purpose of this experiment is to measure the acceleration due to gravity by means of a physical pendulum. The simple pendulum may be defined as a point mass attached to a massless unstretchable string, which is attached to a rigid support.
What is the conclusion of spring constant?
CONCLUSION: From the experiment performed above, it can be concluded that the Hooke’s law holds true for a metal spring. This is because the extension produced by the spring is directly proportional to the force applied on it.
What did Galileo find out about pendulums?
Galileo’s discovery was that the period of swing of a pendulum is independent of its amplitude–the arc of the swing–the isochronism of the pendulum. [1] Now this discovery had important implications for the measurement of time intervals.
What are the sources of error in simple pendulum experiment?
The sources of errors in a simple pendulum experiment are the following: human errors comes in when measuring the period using a stopwatch. The reaction time of the observer plays a significant error when starting the stopwatch and when stopping it. This error can be minimized by repeating the experiment many times.
What is the conclusion for a spiral spring experiment?
Conclusions: Hooke’s Law says that the stretch of a spring is directly proportional to the applied force. (Engineers say “Stress is proportional to strain”.) In symbols, F = kx, where F is the force, x is the stretch, and k is a constant of proportionality.
How do you find the spring constant in an experiment?
W = kx. W is the weight of the added mass. Therefore, the spring constant k is the slope of the straight line W versus x plot. Weight is mass times the acceleration of gravity or W = mg where g is about 980 cm/sec2.
What were the observations that lead to the development of pendulum clock?
Huygens was inspired by investigations of pendulums by Galileo Galilei beginning around 1602. Galileo discovered the key property that makes pendulums useful timekeepers: isochronism, which means that the period of swing of a pendulum is approximately the same for different sized swings.
What is the dependent variable in the pendulum lab?
In this experiment, the period of the pendulum is the dependent variable. There are three independent variables: the pendulum mass, the amplitude of the swing, and the length of the pendulum string.
How can the pendulum experiment be improved?
Other tips: use a low drag bob shape, walls dose to the pendulum cause a problem with relative humidity; slide the top end of the suspension spring up and down through a narrow slot; keep the number of piece parts and mechanical joints in a pendulum to a minimum.
How do you reduce uncertainty in a pendulum experiment?
Reduce the uncertainty in a measurement of periodic time by:
- measuring many oscillations to calculate the average time for one oscillation.
- increasing the total time measured for multiple swings.
What is the conclusion in a hookes law experiment?
What is the meaning of the letter K when we a talking about the extension of springs?
Extension and compression spring constant (k) is measured in newtons per metre (N/m) extension (e), or increase in length, is measured in metres (m)
What are the independent and dependent variable in the pendulum experiment?
3 The three pendulum variables In this experiment, the period of the pendulum is the dependent variable. There are three independent variables: the pendulum mass, the amplitude of the swing, and the length of the pendulum string.
What is the independent variable in the pendulum experiment?
The three variables in Experiment-1 Simple pendulum: Independent variable: The independent variable in this experiment is the length of the string of the pendulum that could be changed. Dependent variable: The dependent variable is the time period for one oscillation.
