It is the length of the pendulum that matters (for small angles of swing):
period ~= 2{pi}sqrt(length/g)
Note that the "length" specified above is the length between the pivot and the centre of the mass of the pendulum, which is usually somewhere near the centre of the bob due to lightweight string and heavy bob on the end.
Pennies (1d coins) are used to adjust the period of the clock in St Stephen's tower of the UK's Parliament building (of which the hour bell is Big Ben) not by adjusting the weight of the bob, but by adjusting the centre of the mass of the bob by stacking the coins towards the pivot.
What else can I help you with?
What effect would the temperature have on the time kept by pendulum clock if the pendulum rod increased in length with an increase in temperature?
A longer pendulum will result in a longer period. The clock would go slower.
Relationship between period of pendulum and length?
The longer a pendulum is, the more time it takes a pendulum takes to complete a period of time. If a clock is regulated by a pendulum and it runs fast, you can make it run slower by making the pendulum longer. Likewise, if the clock runs slow, you can make your clock run faster by making the pendulum shorter. (What a pendulum actually does is measure the ratio between time and gravity at a particular location, but that is beyond the scope of this answer.)
How long does a clock pendulum need to be for a swing of 0.75 seconds?
Use the formula T = 2Pi * Square root (L)/ Square root (g) Set T to .75; L is length of string and g is gravity (9.8 m/s)
Where did Christiaan Huygens invent the clock?
His pendulum clock was patented in 1657.

How can kids make pendulum clocks?
Kids can make pendulum clocks using simple materials such as cardboard, string, a weight (like a small bag of sand or beans), and a paperclip or small washer for the pendulum. They can cut out a circular shape from cardboard for the clock face, attach the weight to the end of the string, and hang it from the center of the clock face. By adjusting the string length, they can regulate the timing of the pendulum swings to create a functioning clock.
How do different lengths of string effect a pendulums swing?
As the length of the string (or armature) of the pendulum increases the rotational speed of the pendulum decreases proportionately if the velocity of the weight remains the same. Example: a pendulum operating a clock is rotating too fast. The clock is running fast as a result. by sliding the pendulum weight out away from the fulcrum (lengthening the armature in effect) the pendulum slows and corrects the time keeping accuracy of the clock. * note: Metronomes operate using this principle as well.
A slow running pendulum clock can be sprreded up by?
A slow pendulum clock is sp[eeded up by decreasing the effective length of the pendulum. The weight on the pendulum is usually mounted such that it can be slid up and down the swinging arm. Sliding the weight up slightly decreases the effective length of the pendulum, and slightly increases the rate at which the clock runs. It should be done only in tiny adjustments, because the size of the change might not even be noticeable until a day or two later.
What if your grandfather clock's pendulum has a length of 0.9930 m If the clock loses half a minute per day how should you adjust the length of the pendulum?
To adjust the length of the pendulum to correct the time lost, you would need to increase the length of the pendulum slightly. Increasing the length will decrease the time period of oscillation, causing the clock to run slower. You would need to experiment with increasing the length incrementally until the clock keeps time accurately.
How do you adjust a pendulum on a clock?
To adjust a pendulum on a clock, you can change the length of the pendulum by moving the pendulum suspension nut up or down. Shortening the pendulum raises the clock’s tempo, while lengthening it slows it down. Make small adjustments and observe the effect on the clock's timekeeping until you achieve the desired accuracy.
What is the principle behind pendulum clock?
A pendulum clock operates on the principle that the period of a pendulum (the time it takes to swing back and forth) is constant and determined by the length of the pendulum. By counting the swings of the pendulum, the clock can keep time accurately. The mechanism of the clock uses gears to translate the regular swinging motion of the pendulum into the movement of the clock's hands.
What happen to the time period if its lenght of the pendulum is changed?
The time period of a pendulum is directly proportional to the square root of its length. If the length of the pendulum is increased, the time period will also increase. Conversely, if the length is decreased, the time period will decrease.
Would you find a pendulum on a colck?
Yes, a clock can have a pendulum. Pendulum clocks use a swinging weight on a rod to regulate its timekeeping mechanism. The swing of the pendulum controls the movement of the clock's hands.
Does with temperature the pendulum of certain pendulum of clock increase?
Yes, as temperature increases, the length of a pendulum in a clock will also increase due to thermal expansion of the material. This change in length can affect the period of the pendulum's swing, potentially causing it to speed up or slow down slightly.
What is the definition of a pendulum?
A large weight that regulates timing in a clock.
Should you turn the screw up or down to make a pendulum go faster on a clock?
Turning the screw up will make the pendulum go faster on a clock. The screw adjusts the length of the pendulum, and a shorter pendulum will swing faster.
Where did the pendulum come from?
The concept of a pendulum has been known since ancient times. However, the modern pendulum clock was invented by Dutch scientist Christiaan Huygens in 1656. He discovered that a weight on a string would swing back and forth with a constant period, making it ideal for timekeeping.
