A simple pendulum is a mass hanging from a massless string of length L is allowed to swing from a central pivot point. As the mass is moved from its center point, gravity pulls the mass down and tension in the string pulls the mass back towards the center point. The mass continues past the center point while the tension force slows it down and pulls it back towards the center point again. This type of motion is known as simple harmonic motion.

Simple Pendulum Example Problem – Find the Length of a Pendulum

Pendulums are in common usage. For small displacements, a pendulum is a simple harmonic oscillator. A simple pendulum is defined to have an object that has a small mass, also known as the pendulum bob, which is suspended from a light wire or string, such as shown in Figure 1.

Exploring the simple pendulum a bit further, we can discover the conditions under which it performs simple harmonic motion, and we can derive an interesting expression for its period. Now, if we can show that the restoring force is directly proportional to the displacement, then we have a simple harmonic oscillator. This result is interesting because of its simplicity. 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.

Consider the following example. What is the acceleration due to gravity in a region where a simple pendulum having a length This is why length and period are given to five digits in this example.

Cut a piece of a string or dental floss so that it is about 1 m long. Attach a small object of high density to the end of the string for example, a metal nut or a car key.

How might it be improved? An engineer builds two simple pendula. Both are suspended from small wires secured to the ceiling of a room.

Each pendulum hovers 2 cm above the floor. Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, and the amplitude of the swing. You can vary friction and the strength of gravity.

Notice the anharmonic behavior at large amplitude. Suppose you move from one city to another where the acceleration due to gravity is slightly greater, taking your pendulum clock with you, will you have to lengthen or shorten the pendulum to keep the correct time, other factors remaining constant?

Explain your answer. True or not, what is the length of such a pendulum? What is its frequency? At what frequency do they swing? What is the acceleration due to gravity at its new location?

What time will it read Note that there are two answers, and perform the calculation to four-digit precision. Skip to content Summary Measure acceleration due to gravity.

Example 1: Measuring Acceleration due to Gravity: The Period of a Pendulum What is the acceleration due to gravity in a region where a simple pendulum having a length Check Your Understanding An engineer builds two simple pendula. Figure 2. Pendulum Lab. Glossary simple pendulum an object with a small mass suspended from a light wire or string. Previous: Next: Share This Book Share on Twitter.

Simple Pendulum Viva Questions and Answers

The Acceleration of Gravity g. To measure g by measuring the period of oscillations of a simple pendulum. A computer with Internet connection, a calculator The built-in calculator of the computer may be used. Gravity exerts a force on every object. This force is proportional to the mass of the object.

Modify gravity, mass or friction damping. Drag the pendulum to change the starting position. Or click below to set initial conditions:. The math behind the simulation is shown below. Also available are: open source code , documentation and a simple-compiled version which is more customizable. For small oscillations the simple pendulum has linear behavior meaning that its equation of motion can be characterized by a linear equation no squared terms or sine or cosine terms , but for larger oscillations the it becomes very non-linear with a sine term in the equation of motion.

Ans: yes iii What is the effective length of a simple pendulum? Ans: It is the total length from the point of suspension to the centre of gravity of the bob iv Why do we use heavy bob which is small in size? Ans: A heavy bob has enough restoring force to overcome the air resistances. A small bob has less resistance due to air. So heavy bob, small in sizes is used as bob v What is a seconds pendulum? Ans: It is a simple pendulum whose time period is 2 seconds. It takes one second to move from one extreme position to the other end.


Sample Assessment Questions with answers. 1. How does The purpose of the experiment is to study the motion of a simple pendulum bob and to determine.

Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, the strength of gravity, and the amplitude of the swing. Observe the energy in the system in real-time, and vary the amount of friction.

Поскольку компьютеры находились во включенном состоянии круглые сутки, замок позволял криптографам покидать рабочее место, зная, что никто не будет рыться в их файлах. Сьюзан ввела личный код из пяти знаков, и экран потемнел. Он будет оставаться в таком состоянии, пока она не вернется и вновь не введет пароль. Затем Сьюзан сунула ноги в туфли и последовала за коммандером. - Какого черта ему здесь надо? - спросил Стратмор, как только они с Сьюзан оказались за дверью Третьего узла. - Как всегда, валяет дурака, - сказала Сьюзан.

Соединения долго не. Наконец раздались длинные гудки.

 Четыре на шестнадцать, - повторил профессор. - Лично я проходил это в четвертом классе. Сьюзан вспомнила стандартную школьную таблицу. Четыре на шестнадцать.

Танкадо спровоцировал АНБ на отслеживание его электронной почты, заставил поверить, что у него есть партнер, заставил скачать очень опасный файл. - Линейная мутация… - еле выдавил Стратмор.
