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.
What else can I help you with?
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.
How does the pendulum work to demonstrate the principles of oscillation and gravity?
A pendulum works by swinging back and forth due to the force of gravity. As the pendulum swings, it demonstrates the principles of oscillation, which is the repetitive motion of an object around a central point. Gravity pulls the pendulum downward, causing it to swing back and forth in a predictable pattern.
How pendulum clock work?
A pendulum clock works by using the swinging motion of a pendulum to regulate the movement of the clock's gears. As the pendulum swings back and forth, it ticks off intervals of time, allowing the clock's gears to move at a precise rate. This consistent movement is what keeps the hands of the clock accurately displaying the time.
How does a pendulum clock work?
A pendulum clock works by utilizing the regular swinging motion of a suspended weight on a rod (the pendulum) to regulate the passage of time. The period of the pendulum's swing is usually set to one second, so each swing back and forth represents one second passing. The swinging motion of the pendulum powers the gears in the clock mechanism, allowing the hands to move in a precise and consistent manner to indicate the time.
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.
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.
The weight on a pendulum is called?
The weight on a pendulum is a 'mass' or a 'bob'.
How does the length of a pendulum affect the frequency?
A longer pendulum will have a smaller frequency than a shorter pendulum.
Frictionless pendulum is an example of?
Frictionlist pendulum is an example of the pendulum of a clock, a reversible process, free.
What happens when you double the mass of a pendulum?
Doubling the mass of a pendulum will not affect the time period of its oscillation. The time period of a pendulum depends on the length of the pendulum and the acceleration due to gravity, but not on the mass of the pendulum bob.
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.
How to find the length of a pendulum?
The length of a pendulum can be found by measuring the distance from the point of suspension to the center of mass of the pendulum bob. This distance is known as the length of the pendulum.
