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.
What did Galileo discover while using 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 two variables were being tested in the pendulum swing lab?
The experiment involved swinging a pendulum with different independent variables and diverse variable values. The independent variables altered were: 1) The length of the pendulum. 2) The mass of the pendulum.
What are the sources of error when performing the single 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 variables affect the swing of a pendulum?
The forces of gravity, the mass of the pendulum, length of the arm, friction and air resistance all affect the swing rate.
When did Galileo discover law of pendulum?
From the first scientific investigations of the pendulum around 1602 by Galileo Galilei, the regular motion of pendulums was used for timekeeping, and was the world’s most accurate timekeeping technology until the 1930s.
What is the simple pendulum theory?
A simple pendulum consists of a mass m hanging from a string of length L and fixed at a pivot point P. When displaced to an initial angle and released, the pendulum will swing back and forth with periodic motion. with being the natural frequency of the motion. …
