Accuracy of Clocks

• Analog clocks represent time with hands moving around a dial, allowing for continuous observation.
• Digital clocks display time numerically, reducing the potential for human error in reading.
• Generally, digital clocks are considered more accurate due to their precise numerical representation, but analog clocks can offer clarity in time intervals.

Measuring Volume of Stones

• Volume measurement for irregular stones typically involves water displacement.
• Method involves submerging the stone in water and measuring the amount of water displaced.
• This technique applies Archimedes' principle, stating that the volume of water displaced equals the volume of the stone.

Volume of a Cube

• Volume of a cube is calculated using the formula: Volume = side length³.
• For a cube with a side length of 5 cm, the volume is 5 cm x 5 cm x 5 cm = 125 cm³.
• This measurement assists in various applications, including material calculation for construction.

Precision in Measurement

• Precision refers to the reproducibility of measurements; how consistently results can be repeated.
• A precise measurement yields similar results under unchanged conditions, indicating reliability.
• Distinction between precision and accuracy: accuracy reflects how close a measurement is to the true value, while precision relates to the consistency of results.
