Chapter 8 Class 7 - Measurement of Time and Motion (Curiosity)

🌱 Science and Society - The Need for Precise Time

  • In sports
    Devices record events down to one-thousandth of a second (a millisecond) to find race winners.
  • In medicine
    ECG machines measure millisecond changes in heartbeats.
  • In music
    Digital recordings capture sound thousands of times per second.
  • In smartphones and computers
    Signals are processed in microseconds (one-millionth of a second).

The faster our clocks become, the more they help society.
