The accuracy of a clock refers to how closely its timekeeping matches the true time. Quartz clocks are accurate to within a few seconds per month, while atomic clocks are precise to within one second in millions of years. Everyday precision varies, but modern digital clocks generally offer high accuracy for most practical purposes.

FAQs & Answers

  1. What factors affect clock accuracy? Factors include the type of clock mechanism, environmental conditions, and the materials used in the clock's construction.
  2. How do atomic clocks work? Atomic clocks use the vibrations of atoms to measure time with extreme precision, making them the most accurate type of clock.
  3. What is the most accurate clock in the world? The most accurate clocks are optical lattice clocks, which can maintain precision within one second over billions of years.
