The precautions are:
Some precautions to take while doing a simple pendulum experiment include ensuring the pendulum is hung securely, keeping the amplitude of the swing small to avoid instability, taking measurements at the center of mass of the bob, minimizing air resistance by using a thin string, and ensuring the angle of release is consistent for accurate results.
Two precautions taken to ensure accurate results in a simple pendulum experiment are using a long string to minimize air resistance and ensuring the pendulum swings in a small angle to approximate simple harmonic motion.
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 physical parameters that might influence the period of a simple pendulum are the length of the pendulum, the acceleration due to gravity, and the mass of the pendulum bob. A longer pendulum will have a longer period, while a higher acceleration due to gravity or a heavier pendulum bob will result in a shorter period.
The period of a simple pendulum does not depend on the mass of the pendulum bob. The period does depend on the strength of the gravitational field (acceleration due to gravity) and on the length of the pendulum. A longer length will result in a longer period, while a stronger gravitational field will result in a shorter period.

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.

In theory, a true simple pendulum is an idealized model that assumes a massless string and a point mass that swings in a vacuum without any external forces like air resistance or friction. While we can closely approximate a simple pendulum in practical experiments, achieving a perfect simple pendulum is impossible due to the inherent complexities of real-world materials and conditions. Factors such as the mass of the string, air resistance, and gravitational variations prevent us from creating a true simple pendulum. Thus, while we can create very close approximations, a true simple pendulum remains a theoretical concept.

The period does depend on the strength of the gravitational field (acceleration due to gravity) and on the length of the pendulum. A longer length will result in a longer period, while a stronger gravitational field will result in a shorter period.
A bar pendulum is better than a simple pendulum because it has a larger moment of inertia, making it less affected by external forces like air resistance or friction, leading to more accurate results. Additionally, the bar pendulum has a more linear relationship between its period of oscillation and the length of the pendulum, allowing for easier calculations and predictions.
The main forces at play in a pendulum swing are gravity and tension. Gravity pulls the pendulum bob downward while tension in the string keeps it swinging back and forth. The motion of the pendulum is an example of simple harmonic motion, where the pendulum swings back and forth with a constant period.
A simple pendulum will not swing when it's aboard a satellite in orbit. While in orbit, the satellite and everything in it are falling, which produces a state of apparent zero gravity, and pendula don't swing without gravity.
