Invar is used for pendulum clock why?
Invar is used in pendulum clocks because of its low coefficient of thermal expansion, which makes it less likely to expand or contract with changes in temperature. This helps the clock maintain its accuracy by preventing the pendulum's length from changing due to temperature fluctuations.
Why a compound pendulum is called equivalent simple pendulum?
Compound pendulum is a physical pendulum whereas a simple pendulum is ideal pendulum. The difference is that in simple pendulum centre of mass and centre of oscillation are at the same distance.
Who invented the pendulum?
Christan Huygens invented the pendulum clock in 1659. Christan huygens is a Dutch Scientist.The invention of the pendulum clock is credited to Christian Huygens who developed working versions in the mid 1650's AD. A couple decades earlier, Galileo came up with designs for a pendulum clock, though it was not completed.
What are the limitation of simple pendulum?
The popular formula for the period of a pendulum works only for small angular displacements. In deriving it, you need to assume that theta, the angular displacement from the vertical, measured in radians, is equal to sin(theta). If not, you need to make much more complicated calculations. There are also other assumptions to simplify the formula - eg string is weightless. The swing of the pendulum will precess with the rotation of the earth. This may not work if the pendulum hits its stand! See Foucault's Pendulum (see link). The motion of the pendulum will die out as a result of air resistance. Thermal expansion can change the length of the pendulum and so its period.
Why has my grandfather clock's pendulum stopped swinging?
The most likely explanation is that you need to wind it up. Mechanical clocks, including grandfather clocks, need to be wound every so often. There should be some way to wind up a spring, which you'll see if you open up the clock.
Sources of your thoughts as a believer?
Whilst working with a Dowsing Pendulum.
The worlds oldest pendulum still working is located in?
Oregon and one in California
Where did you last see a pendulum on your daily travels?
There was on in the clock on a friend's mantelpiece.
What is the relationship between the period of a pendulum and its length?
For small angles, the formula for a pendulum's period (T) can be approximated by the formula:T = 2 * pi * sqrt(L/g), where L is the length of the pendulum length, and g is acceleration due to gravity. See related link for Simple Pendulum.
How much time it take if the pendulum is relesed at angle 1.75 degrees instead of 3.5 degrees?
The period of the pendulum is unchanged by the angle of swing. See link.
Could I see an example of rhythmic activities?
- a swinging pendulum - an oscillating spring
Who discover principle of pendulum?
Galileo or Vivaldi. See related link below.

A swinging pendulum is moving fastest at?
A swinging pendulum is moving fastest at the lowest point of its arc. That is the point where all its potential energy has been converted into kinetic energy, and it is the only point in a pendulum's arc where that happens. See related link (a simulation).
Why it is imp to record 10 oscillations in a pendulum?
I assume you want to get the pendulum's period. If you record a greater amount of oscillations, you will reduce the error - since if you manually measure time, you are likely to get an error of a few tenths of a second.
What does a Ellicott Pendulum measure?
An Ellicott pendulum is a temperature compensated clock pendulum. The metal rod of a pendulum changes its length with temperature. The consequence is, that a colder pendulum swings faster (the rod is shorter) and a warm pendulum swings slower (longer rod). The Ellicott pendulum compensates this temperature error of the pendulum. It consists of a steele rod and two brass rods, wich are connectet in one point above the pendulum bob. Brass has a higher temperature coefficient than steele. On the free end of the three rods, a special lever mechanism, controlled by the lenght difference of the rods, lifts the pendulum bob up, when the length of the rods grows. The bob stays at its position and the period of the pendulum is without temperature influence. See also http://commons.wikimedia.org/wiki/File:Ellicott_pendulum.png
Effect of large angle to oscillation?
The motion is likely not to be a simple harmonic motion as required for the formula for the period of a pendulum to work properly. The angle of swing is likely to reduce.
