How do you make a pendulum clock is it the weight or the length of the string?
PuddlesWater
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 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.
What does grandfather clock uses to measure time?
The Pendulum.
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?
make shorter length
What happen to the time period if its lenght of the pendulum is changed?
If the length of a pendulum is increased, the pendulum will take longer to complete a swing, and the clock will slow down. Shortening the pendulum will speed up the clock.
How do you adjust a pendulum on a clock?
The pendulum of a clock is usually constructed with some sort of clamp or sliding catchthat permits sliding the weight up and down the stick, raising or lowering its center of massand thus changing its effective length.-- If the clock is running too fast, and has to be turned back a few minutes every now and then,make the pendulum slightly longer, by sliding the weight down a bit on the stick. This makesthe pendulum swing slightly slower.-- If the clock is running too slow, and has to be turned a few minutes ahead to catch up everynow and then, make the pendulum slightly shorter, by sliding the weight up a bit on the stick.This makes the pendulum swing slightly faster.
What is the definition of a pendulum?
A large weight that regulates timing in a clock.
What Causes of pendulum to swing?
i think that it might be gravity are we talking bout a clock? or someting on a string?
What is the bob of a pendulum?
The bob is the weight at the end of the pendulum. For example, in a grandfather clock the ball at the end of the stick is the bob.
What is a good sentence for the word pendulum?
I have a pendulum clock or my dog's tail swung like a pendulum when he heard the jingle of his lead. Dictionary definition for pendulum- A weight hung from a fixed point so that it can swing freely backward and forward, esp. a rod with a weight at the end that regulates the mechanism of a clock.
What is the scientific theory of a pendulum?
The theory of a simple pendulum refers to a relatively huge object hanging vertically by a string from a fixed place and moving in a back and forth motion when displaced. The movement of the huge object or pendulum bob is repetitive and regular.
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.
