A pendulum is a weight suspended from a pivot that swings back and forth under the force of gravity. It is commonly used in timekeeping mechanisms like clocks and metronomes due to its regular and predictable motion. Pendulums are also used in physics experiments to demonstrate concepts like oscillation and harmonic motion.

What is the Lagrangian formulation for a rotating pendulum?
The Lagrangian formulation for a rotating pendulum involves using the Lagrangian function to describe the system's motion. This function takes into account the kinetic and potential energy of the pendulum as it rotates, allowing for the equations of motion to be derived using the principle of least action.
What are the advantages of pendulum clocks?
Pendulum clocks are accurate timekeepers due to the periodic motion of the pendulum, which helps regulate the movement of the clock's gears. They are also relatively simple in design, making them reliable and easy to maintain. Additionally, pendulum clocks are energy-efficient as they require minimal power to function.
What type of simple machine is a pendulum contraption?
A pendulum contraption is typically classified as a compound machine, as it combines multiple simple machines like a lever, a wheel and axle, and potentially a pulley system to function.
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.
The weight on a pendulum is called?
The weight on a pendulum is a 'mass' or a 'bob'.

Does the length of pendulum affect the period of vibration?
Yes. Given a constant for gravity, the period of the pendulum is a function of it's length to the center of mass. In a higher gravity, the period would be shorter for the same length of pendulum.
Absolute value function in real life?
The displacement, from the vertical, of a child on a swing, or a pendulum.

A pendulum contraption is typically classified as a compound machine, as it combines multiple simple machines like a lever, a wheel and axle, and potentially a pulley system to function.
Why is a pendulum clock useless at sea?
A pendulum clock is useless at sea primarily due to the constant motion and rocking of the ship, which disrupts the pendulum's ability to swing freely and maintain accurate timekeeping. The pendulum relies on gravity to function properly, and the shifting forces on a moving vessel can lead to inaccuracies in time measurement. Additionally, variations in gravitational pull depending on location can further complicate the clock's reliability.
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'.
Frictionless pendulum is an example of?
Frictionlist pendulum is an example of the pendulum of a clock, a reversible process, free.
How does the length of a pendulum affect the frequency?
A longer pendulum will have a smaller frequency than a shorter pendulum.
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.
