The most ancient and well known is the sundial. Sundials have existed for thousands of years.
Another method was the graduated candle. A candle of a known composition and thickness was marked into divisions and lit. By sitting the candle in a metal bowl and sticking a nail in at a certain point, a timing device or alarm clock could be created.
The dripping of water at a steady rate between two vessels was another early method of measuring time.
These two latter methods could be calibrated accurately by marking them in daylight whilst sitting next to a sundial.
The Chinese were the first people to create a machine that could measure elapsed time by the controlled release of a spring or weight. Likewise the machine could be calibrated in daylight and would then render accurate time throughout the night.

What scientific instruments are used to measure speed?
Instruments used to measure speed include radar guns, LIDAR devices, and GPS units. These instruments work by calculating the speed of an object based on its distance traveled over time.
Name Some measuring instruments and their uses?
Tape measure: used to measure distances and lengths. Scale: used to measure weight or mass. Thermometer: used to measure temperature. Ruler: used to measure small lengths or distances. Stopwatch: used to measure time or duration.
Why did they make a water clock?
Ancient civilizations created water clocks to measure time based on the flow of water. Water clocks allowed people to track time more accurately for activities like farming, cooking, and religious ceremonies. They were a simple and reliable way to divide the day into smaller units.
What do sciencetists to measure speed?
Scientists use various instruments to measure speed, such as radar guns, Doppler radar, and stopwatch. Radar guns emit radio waves to measure the speed of moving objects, while Doppler radar uses reflected signals to calculate speed. Stopwatches are used to measure the time it takes for an object to travel a known distance, allowing for the calculation of speed.
How have string intruments changed over time?
String instruments have evolved over time with advancements in technology and materials. Early string instruments were made from natural materials like animal gut and wood, while modern instruments often use synthetic materials. Additionally, the construction and design of string instruments have been refined over time to improve their sound quality and playability.
How did ancient people measure time?
The sun, the stars.
How did people in ancient times measure time in months and days?
they checked it by checking the position of the planets.
Name some instruments that were invented to measure time?
an hourglass
What r clocks?
They are (not "r") instruments used to measure time.
What are the different ways ancient people use to measure time?
Using the: -Sun -Moon -Seasons - Tides
Why did people need to measure time in ancient times?
cuz they felt like it yo yo yo
When did people start using the concept of "years" to measure time?
The concept of "years" to measure time began around 3000 BCE in ancient civilizations like the Sumerians and Egyptians.
What scientific instruments are used to measure speed?
Instruments used to measure speed include radar guns, LIDAR devices, and GPS units. These instruments work by calculating the speed of an object based on its distance traveled over time.
Why did people use hourglasses?
To measure time. To measure time. To measure time.
What did people wear in ancient time?
What people wore in ancient time varied from civilisation to civilisation.

Name the instruments necessary to measure each of the above quantities which are known by the units which they measure?
To measure various physical quantities, different instruments are used based on the type of quantity being measured. Here are some examples: Length: Measured in meters (m). Instruments used to measure length include rulers, tape measures, and calipers. Mass: Measured in kilograms (kg). Instruments used to measure mass include balances and scales. Time: Measured in seconds (s). Instruments used to measure time include clocks and stopwatches. Temperature: Measured in degrees Celsius (°C) or degrees Fahrenheit (°F). Instruments used to measure temperature include thermometers. Electric current: Measured in amperes (A). Instruments used to measure electric current include ammeters. Voltage: Measured in volts (V). Instruments used to measure voltage include voltmeters. Frequency: Measured in hertz (Hz). Instruments used to measure frequency include oscilloscopes and frequency counters. Pressure: Measured in pascals (Pa). Instruments used to measure pressure include barometers and manometers. There are many other physical quantities that can be measured, and different instruments may be used depending on the specific quantity and the required precision of the measurement.
