Centrifugal force is a fictitious force that appears to act on an object moving in a circular path, causing it to move away from the center of the circle.
It is a result of the inertia of the object, which tends to keep it moving in a straight line.

This is a statement of Newton's second law of motion, which states that the force (F) required to accelerate an object is proportional to its mass (m).
The weight of a body is the force exerted on it by gravity.
It depends on the gravitational pull of the planet or moon it is on.
Since the gravitational pull varies from place to place (it is stronger near the surface of the Earth than on a mountain, and weaker on the Moon than on the Earth), the weight of a body also varies.
These six quantities (length, mass, electric current, time, intensity of light, and amount of substance) are the fundamental base quantities in the International System of Units (SI).
They are the basic building blocks of the SI system and are used to define all other quantities.
If the zero line of the Vernier scale coincides with the zero of the main scale, it means that there is no zero error.
Zero error occurs when the zero of the Vernier scale is not aligned with the zero of the main scale, resulting in a systematic error in the measurements.
Significant figures (also known as significant digits) are the number of digits in a measurement or calculation that are known to be reliable and accurate, including the first doubtful digit.
For example, the measurement "23.4 cm" has four significant figures, while "23.40 cm" has five significant figures.
