- Simple Pendulum | Science Experiment
A simple pendulum consists of a metallic ball (called bob) hung by a perfectly inextensible and weightless string.
When a bob is at rest position in a straight line, it is in its mean position.
When the bob is displaced from its mean position and then released, it makes to and fro movement about its mean position.
If the pendulum moves from one extreme position to the other and back to the first it is said to have performed one oscillation.
Time Period :- The time period of the simple pendulum is defined as the time required by the pendulum to complete one oscillation.
Frequency :- The frequency of the simple pendulum is defined as the number of oscillations performed per unit time.
The length of a simple pendulum is the length from the point of suspension to the centre of the ball.
Let us perform an experiment to observe that the time period varies with the length of the pendulum.
1. Suspend the bob by a perfectly in extensible and weightless string.
2. Measure the length of the string (L) from the point of suspension and the centre of the bob.
3. Gently pull the bob pendulum from one extreme end in such a way that it moves from one extreme position to the other and back to the first .(one complete oscillation)
4. Take a stopwatch and record the time a pendulum takes to complete 10 oscillations.
5. Time period of simple pendulum will be time taken to complete 10 oscillations divided by number of oscillations.
6. Repeat the process with different length of pendulum.
7. Plot the graph with time (T) on x-axis and length (L) on y-axis.
8. You will get a curve graph.
9. From this graph we infer that time period varies with the length of the pendulum.

Legands watching the video before 1 hrs before the exam
Thank you so much for this. Appreciated!
Glad it was helpful!
How do Mechanical engineers calculate the formula of T = the time when the pendulum has practically STOPPED oscillating? accounting all the forces of Air resistance, drag, attachment friction etc...etc. Thank You.
This is very useful for my project, thank you for making this video
Glad it was helpful!
amazing, thank you this made me clarify my doubt
Glad it helped!
Is a pendulum oscillation is similar to breathing,eyeball movement
This is so good and it helps me alot
Thankyou 🙂
An oscillator is a device that exhibits motion around an equilibrium point. In a pendulum clock, there is a change from potential energy to kinetic energy with each swing.
Thanks. It really helped me
Glad it helped!
Thank you it made my understanding better
Glad to hear it!
Hii
It helped me alot
Glad it helped u
It helped me too
Nice video, thanks
Glad you liked it!
The best explanation so far
Glad it was helpful!
thank you very much 🥰
Most welcome
VERY VERY USEFUL FOR SCIENCE TEACHERS
Thanks a lot
isn't "time in sec" (time period) the dependent variable and length in cm independent variable. so why not plot "time in sec" in Y-axis and "length in cm" in X-axis?
HIGH QUALITY VIDEOS AND VIRTUAL LAB ZINDABAD
its always good to see ur comment
Thank u sir ❤️
u r welcome
What is oscillation
Bob is hitting the stand....
PLEASE MAKE VIDEO ON MULTIPLE REFLECTION AND MULTIPLE IMAGES
sure we will...
👍
Good Video
Great...happy u liked it
Thanks sir...😁😁
welcome
very Nice
Good morning man
Thank youuuuuu
My pleasure
Upload more videos of physics 😊
It is helpful ☺️
sure we will
How to make
Our teacher recommended this video.
Nice
Thanks
how to create 24 hours and 45 minutes?
like for example on mars planet
I done this but....idk why but the value of g was 7.61 even after doing it after 10 times
My stopclock messed up my reading
IT HEPED ME VERY MUCH FOR MY PHYSICS PROJECT. THANK YOU FOR THIS VIDEO 🙏🙏
Great it helped...pls keep watching
بيندلم😂
Ok
