What does a fixed variable mean in science?
A variable within an experiment that remains the same. Such as the weight of a pendulum.
What are applications in a science fair experiment?
easy
What is the controlled variable in pendulum experiment?
It depends on the experiment... but the possible constants for such an experiment could be...The mass of the weight at the end of the string (which is independent from the SHM)The length of the stringThe height of the weight when released (not necessarily)Then given that you don't need to put on would be the gravitational force of acceleration 9.81 ms-2, etc.
When is an experimental variable good and when should it be reduced or eliminated?
There are generally 3 variable in an experiment : the dependent, independent and the control variable. The independent variable is something you change in your experiment and affects the dependent variable, while the control variable is there to make sure the experiment is a fair test. (eliminate external factors) A variable is considered good when it allows you to find a relationship or to investigate your theory. eg. A simple experiment : To investigate whether length of pendulum affects the period of a pendulum. IN this case, your independent variable would be the length of pendulum(to be changed) while your dependent variable is the time taken for 1 oscillation. You can plot x-y graphs to find the relationship between the two to help you conclude your experiment. ( Wind factor should be eliminated as it will affect your readings). There is no control variable for this experiment as period is dependent only on length and gravity.(unless gravitational force changes) There are times when a variable can be affected by many other factors. So in your experiment, you might want to eliminate those factor so that you can make a conclusion.

What is the effect of draught in a simple pendulum experiment?
In a simple pendulum experiment, air resistance or drag can affect the motion of the pendulum by slowing it down. This can lead to discrepancies in the period and amplitude of the pendulum swing compared to theoretical calculations. It is important to minimize the effects of air resistance in order to obtain accurate results in the experiment.
Would be value of g be affected if the size of the Bob is varied in simple pendulum experiment?
No, the value of acceleration due to gravity (g) would not be affected by changing the size of the bob in a simple pendulum experiment. The period of a simple pendulum is determined by the length of the pendulum and the gravitational acceleration at that location, not the size of the bob.
Can you conduct simple pendulum experiment at the centre of the earth?
It would not be possible to conduct a simple pendulum experiment at the center of the Earth due to extreme heat and pressure conditions. Additionally, the gravitational force at the center of the Earth would be effectively zero, which is essential for the functioning of a simple pendulum.
What is Purpose of simple pendulum experiment?
The purpose of a simple pendulum experiment is to investigate the relationship between the length of the pendulum and its period of oscillation. This helps demonstrate the principles of periodic motion, such as how the period of a pendulum is affected by its length and gravitational acceleration. It also allows for the measurement and calculation of physical quantities like the period and frequency of oscillation.
What are the medical applications of a simple pendulum?
A simple pendulum can be used in medical applications to measure a patient's pulse rate. By counting the number of swings of the pendulum in a given time period, a healthcare provider can determine the patient's heart rate. This can be a simple and effective way to monitor a patient's vital signs in certain situations.
What are the physical and medical applications of the simple pendulum experiment?
1- Walking: Some aspects of walking can be analyzed in terms of the simple harmonic motion of a pendulum. The motion of one foot in each step can be considered as approximately a half-cycle of a simple harmonic motion. 2- Energy Expended in Running: During each step of the run, the leg is accelerated to a maximum angular velocity ωmax. In our pendulum model, this maximum angular velocity is reached as the foot swings past the vertical position =0. 3- Carrying Loads.
How do you write a simple pendulum lab report?
To write a simple pendulum lab report, start by stating the objective of the experiment and provide a brief background on the physics of a simple pendulum. Include a description of the experimental setup, procedure, and data collected. Analyze the data, calculate relevant parameters like the period of the pendulum, and present your results in tables and graphs. Conclude with a summary of your findings and any sources of error in the experiment.
What is the easiest experiment to measure gravitational field strength?
The easiest experiment to measure gravitational field strength is to use a simple pendulum. By measuring the period of oscillation of the pendulum, you can calculate the gravitational field strength based on the known length of the pendulum and the formula for the period of a simple pendulum.
Why is a simple pendulum bob preferred to bobs of irregular shapes for use in the simple pendulum experiment?
it is less ffected by air resistance
Conclusion of simple pendulum experiment?
Well, well, well, look who's wrapping up their simple pendulum experiment! The conclusion should summarize the findings, discuss any sources of error, and suggest improvements for future experiments. Make sure to mention how the results align with the theory of simple harmonic motion, and don't forget to throw in some scientific jargon to really impress your teacher. Now go on, show 'em what you've got!
