A simple pendulum is a mass attached to a fixed length string or rod, with its time period dependent on length and gravity. Vernier calipers use a movable vernier scale for accurate measurements. The concept of 1 kilogram on an atomic scale refers to mass based on specific atoms.
A simple pendulum consists of a mass (bob) attached to a string or rod of fixed length. The time period of a pendulum depends on its length and the acceleration due to gravity.
The principle of vernier calipers involves the use of a movable vernier scale to measure accurately the internal and external dimensions of an object.
1 kilogram on an atomic scale refers to the mass of a specific number of atoms, based on the mass of a reference atom like carbon-12.
Backlash error is the looseness in mechanical systems that can cause misalignment. It is avoided by minimizing clearances and ensuring proper alignment of components.
