Question: How Can You Make A Pendulum Experiment More Accurate?

How do you do the pendulum experiment?

An example pendulum experimental setup.Measure the period of your pendulum.

Pull the weight of the pendulum back about 30 degrees.

Repeat steps 1–2 for your other pendulum lengths.

Record all your results in your data table.For each pendulum length, calculate an average period.

Analyze your data..

Why do shorter pendulums swing faster?

The only factor that significantly affects the swing of a pendulum on Earth is the length of its string. … A pendulum with a longer string has a lower frequency, meaning it swings back and forth less times in a given amount of time than a pendulum with a shorter string length.

What affects the oscillation of a pendulum?

The only things that affect the period of a simple pendulum are its length and the acceleration due to gravity. The period is completely independent of other factors, such as mass. … If the length of a pendulum is precisely known, it can actually be used to measure the acceleration due to gravity.

Does the mass of a pendulum affect its period?

The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. Two pendula with different masses but the same length will have the same period. Two pendula with different lengths will different periods; the pendulum with the longer string will have the longer period.

Why mass does not affect pendulum period?

The mass on a pendulum does not affect the swing because force and mass are proportional and when the mass increases so does the force. As the force increases so does the acceleration and along with gravity are the factors that affect the pendulum swing. … Mass does not affect the period of the pendulum.

How do I keep my pendulum swinging?

There are several things that you can do to make a pendulum swing for a long time:Make it heavy (and, specifically, dense). The more mass a pendulum has, the less outside influences such as air resistance will degrade its swing.Put it in a vacuum. … Use an escapement mechanism.

What is the aim of the pendulum experiment?

The purposes of this experiment are: (1) to study the motion of a simple pendulum, (2) to study simple harmonic motion, (3) to learn the definitions of period, frequency, and amplitude, (4) to learn the relationships between the period, frequency, amplitude and length of a simple pendulum and (5) to determine the …

How do you accurately measure the length of a pendulum?

A simple way to measure the pendulum’s period fairly precisely is to start the pendulum swinging, and measure the time required for a large number of FULL swings – 40, 50, or so. Choose the number of swings so that the total time for the measurement is 40 seconds or more.

How can the of a pendulum be increased?

The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.)

What cause a pendulum to come to a stop?

The main reason the pendulums stop is due to air friction and the friction at the point of rotation. To see a pendulum that removes one of these sources of friction, you can see a Coriolis force clock. These are pendulums that swing but instead of being on a pivot point, they are held up magnetically.

What is the purpose of the pendulum experiment?

The goal of this experiment was to determine the effect of mass and length on the period of oscillation of a simple pendulum. Using a photogate to measure the period, we varied the pendulum mass for a fixed length, and varied the pendulum length for a fixed mass.

What are the variables in a pendulum experiment?

The independent variable was the point of release and the dependant variable was the period. The controlled variables were the length and mass of the pendulum. Before we did the experiment, we were unsure of whether or not the independent variable affected the period.

What is period of oscillation?

The time to complete one oscillation remains constant and is called the period T. Its units are usually seconds, but may be any convenient unit of time.

How can you use a pendulum to measure time?

Calculate the time of one oscillation or the period (T) by dividing the total time by the number of oscillations you counted. Use your calculated (T) along with the exact length of the pendulum (L) in the above formula to find “g.” This is your measured value for “g.” Repeat the above procedure for 3 more cases.

What are sources of error in an experiment?

Common sources of error include instrumental, environmental, procedural, and human. All of these errors can be either random or systematic depending on how they affect the results. Instrumental error happens when the instruments being used are inaccurate, such as a balance that does not work (SF Fig. 1.4).

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. … instrument errors – using a digital stopwatch also introduce errors. … The arc angle also introduce errors.

What happens to the period of a pendulum when the mass is doubled?

a) If the length is doubled, the period will increase by a factor of √2 . Doubling the mass of the bob will half the period.

What affects the swing rate 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.

Do heavier pendulums swing faster?

A heavier pendulum will not swing faster. The mass of the pendulum will not have any effect on the period of the swing as we can observe in the next…

What is one oscillation of a pendulum?

The pendulum is said to have completed one oscillation when its bob,starting from its mean position O, moves to A, to B and back to O. The pendulum also completes one oscillation when its bob moves from one extreme position A to the other extreme position B and comes back to A.

How does air resistance affect a pendulum?

In a vacuum with zero air resistance, such a pendulum will continue to oscillate indefinitely with a constant amplitude. However, the amplitude of a simple pendulum oscillating in air continuously decreases as its mechanical energy is gradually lost due to air resistance.
