Some of the possible errors are due to the fact that the experiment relies on ideals that can be physically approximated but not actually realised. Examples include inelastic, weightless string, the contact between the pivot and string, and between the string and bob being points, the bob being point mass.
External factors, such as vibrations and gusts of wind can affect a pendulum's swing.
The acceleration due to gravity varies from place to place and so the formula must be calculated for the local value of g, not the generally accepted average of 9.8 ms^-2.
The formula for the period of a pendulum is accurate only for small angular displacements. At only 3 degrees, the difference in the measured period and that given by the formula is 15 seconds per day!
The length of a pendulum is the distance from the pivot to the centre of mass of the bob. However, this distance may not be easy to measure: it may require the assumption that the bob is made of uniform material.
And then there are errors in measuring the time intervals.

What is a penny dropper?
A penny dropper refers to someone who intentionally drops a penny on the ground with the intent of seeing if anyone picks it up. It can be used as a form of social experiment or to gauge people's honesty.
What happens to the copper atoms of the penny in gold penny lab?
basically, the zinc electrons in the NaOH solution coat the copper penny and then when you wave it over a Bunsen burner, the two metals form an alloy (a homogeneous mixture with two or more elements) and make brass, not gold.
What is a 1943 penny nickel mix with copper?
A 1943 penny could be a "steel penny" as they were made of steel due to copper being needed for other wartime purposes. Nickels were made of 35% silver during WWII. If a 1943 penny and nickel were mixed, it would potentially be an error as they wouldn't have been in circulation together due to their different compositions.
Can you clean a penny with rubbing alcohol?
Yes BUTTTTT ....NEVER, EVER try to clean valuable coins to make them "look better". Dumping a modern penny in Coke to see what happens is a good chemistry experiment, but don't try it with an Indian penny from your grandfather's coin collection because it'll go from being worth possibly several dollars as a collectible, down to only a cent or two as a damaged coin.
What are the dependent and independent variables in cleaning pennies experiment?
Independent variable: This is the one you're changing in the experiment, so it's the type of solution that you're dropping on the penny. Dependent variable: This is the one that you're measuring. In this case, it's how many drops you can get onto a penny without the water spilling off. Control variable: These are things that you keep the same throughout all of the experiments to make sure that your results are actually due to the changes in the independent variable, not some other random change you made. You used the same penny and dropper.
What is the value of an error penny?
Ask another question and include the date and type of error on the penny.
How do you measure inertia of a penny?
Measuring the inertia of a penny can be done by equation or experiment. The experiment is as simple as placing the penny on a piece of cardboard on top of a cup. Flick the cardboard, which will move, and the penny just falls into the cup.
What is the control on the penny water drops experiments?
In this experiment, the control group would be the penny! The independent variable is the substance/water on the penny, and the dependent is how many drops the penny takes.
Does bleach rust a penny faster than water?
Yes it does I did an experiment on it
1942 Wheat Penny date reads C942 is that rare?
This is considered an "error coin" and is rare. Depending on the "eye appeal", rarity and significance of the error, the penny may be moderately valuable.
What is the hypothesis of penny drop?
The hypothesis of the penny drop experiment is that the design of the container, the height from which the penny is dropped, and the amount of water in the container will affect whether the penny lands heads up or heads down.
What is the rarest Lincoln Penny?
The rarest and most valuable Lincoln cent that isn't an error is the 1909-S with VDB on it. The rarest and most valuable error Lincoln cent is the 1943 copper penny.
What is the value of a penny with Lincoln head and the Memorial stamped on one side with the other side blank?
This type of error of misstruck coins is called 'Brockage'. A Lincoln penny with this error is valued at $35.00
What is the value of an 1849 penny with an error on it?
Without knowing the condition of the coin, and the type of error, there is no way to tell its value.
What do you use a histogram for?
You use the histogram for like an experiment,like a penny lab
When conducting an experiment of surface tension of water on a penny what is the independent variable?
Temperature.
What is a 1828 penny with an error on it worth?
The value of any error coin depends upon the nature of the error. Please examine your coin and submit a new question describing the error.
