Newton's three laws of physics describe the concept of force. The laws of force are only valid in "inertial reference frames," which means that they are only correct according to observers that are not accelerating (i.e. observers that are either standing still, or moving with constant speed).
The Earth is NOT an inertial reference frame (though for most cases it can be approximated as one, since the acceleration of an object on Earth is small). Since Earth is accelerating, Newton's laws are not 100% valid according to someone that is rotating with Earth. What this means is that a person on Earth, measuring the force on some object on Earth, will find that there are forces acting on the object which have no actual cause via interaction with other objects.
Due to Earth's rotation, an object moving along the surface of Earth with some velocity will appear to have a force acting on it which causes it to travel in a circle. A Foucalt pendulum exhibits this phenomenon. The pendulum seems to change its swinging direction at the same rate as Earth's rotation. See Wikipedia.org/wiki/Foucault_pendulum for some animations on this.

How does the length of the pendulum effect the pendulum?
The longer the length of the pendulum, the longer the time taken for the pendulum to complete 1 oscillation.
How does the length of a pendulum affect the frequency?
A longer pendulum will have a smaller frequency than a shorter pendulum.
Which factor affects the period of the pendulum?
The period of a pendulum is affected by the angle created by the swing of the pendulum, the length of the attachment to the mass, and the weight of the mass on the end of the pendulum.
What are difference between simple pendulum and compound pendulum?
A simple pendulum has one piece that swings. A complex pendulum has at least two swinging parts, attached end to end. A simple pendulum is extremely predictable, while a complex pendulum is virtually impossible to accurately predict.
How can you increase the period of a pendulum?
Increase the length of the pendulum
How would you use 'pendulum' in a sentence?
Caroline and Jarred asked Mrs.West about how a pendulum works.
Does the torsional pendulum depend on acceleration due to gravity?
No, a torsional pendulum works with the restoring force provided by the elasticity of the support rod, or (in clocks and watches) by the spring on the balance-wheel.
How does each part of the pendulum work?
A pendulum could be almost anything, even a soap on a string. They're not picky, so I can't really say I know how each part works.
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.
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.
What effect does shortening the length of the pendulum have on the period of the pendulum?
A shorter pendulum has a shorter period. A longer pendulum has a longer period.
How does the length of the pendulum effect the pendulum?
The longer the length of the pendulum, the longer the time taken for the pendulum to complete 1 oscillation.
What is flashing pendulum?
maybe it is a pendulum
What is a bifilar pendulum?
bifilar pendulum
Which swing more heavier pendulum or lighter pendulum?
A heavier pendulum will swing longer due to its greater inertia.
How did the seismograph of Chang Heng Works?
historians believe there was a pendulum inside and when an earthquake hit, the pendulum swung causing it to hit a lever which would cause a dragon facing the direction of the quake to drop its copper ball into the mouth of a toad below
What are the physical parameters in the investigation of a simple pendulum?
The physical parameters of a simple pendulum include (1) the length of the pendulum, (2) the mass of the pendulum bob, (3) the angular displacement through which the pendulum swings, and (4) the period of the pendulum (the time it takes for the pendulum to swing through one complete oscillation).
