Its length.
Yes. Given a constant for gravity, the period of the pendulum is a function of it's length to the center of mass. In a higher gravity, the period would be shorter for the same length of pendulum.
The period of a pendulum that takes one second to complete a to-and-fro vibration is one second. This means it takes one second for the pendulum to swing from one extreme to the other and back again. The period is the time it takes for one complete cycle of motion.
In a pendulum experiment, the independent variable is typically the length of the pendulum or the angle of release, as these are manipulated by the experimenter. The dependent variable is usually the period of the pendulum, which is the time taken for one full swing back and forth.
Since T=2pi*sqrt(l/g) and l is the only variable that effects T that is the period it is the length.
Galileo's pendulum experiment showed that the period of the swing is independent of the amplitude (size) of the swing. So the independent variable is the size of the swing, and the dependent variable is the period. The experiment showed there was no dependence, for small swings anyway. The experiment led to the use of the pendulum in clocks.
Approximately 2*pi*sqrt(l/g) where l is the length of the pendulum (in metres) and g = 9.8 ms-2, the acceleration due to gravity.
A complete back and forth vibration, also known as a full oscillation, for a pendulum with a period of 1.5 seconds would take a total time of 3 seconds. This time includes both the movement to one side and back to the starting point.
Hardly at all, at small displacements or amplitudes. At larger displacements (larger angles), the period will get somewhat longer.
The period of a pendulum is directly proportional to the square root of its length. As the length of a pendulum increases, its period increases. Conversely, if the length of a pendulum decreases, its period decreases.
The length of the pendulum affects its frequency - a longer pendulum has a longer period and lower frequency, while a shorter pendulum has a shorter period and higher frequency. The gravitational acceleration also affects the frequency, with higher acceleration resulting in a higher frequency.
Suppose that a pendulum has a period of 1.5 seconds. How long does it take to make a complete back and forth vibration? Is this 1.5 second period pendulum longer or shorter in length than a 1 second period pendulum?
The period of a pendulum is not affected by the mass of the pendulum bob. The period depends only on the length of the pendulum and the acceleration due to gravity.
