- Answer Wiki. There is really only one measure of time, and that is hours/minutes/seconds/days/weeks/months/years. Then you have derivations of these including Lunar years, light years, periods between full moons, days (between sun rises), but they all come back to the traditional time of hours/minutes/seconds.

A Brief History of Time Measurement Originally, sandglasses were used as a measure for periods of time like the lamps or candles, but as clocks became more accurate they were used to calibrate sandglasses to measure specific periods of time, and to determine the duration of sermons, university lectures, and even periods of torture.

History of timekeeping devices The hourglass was one of the earlier timekeeping devices and has become a symbol of the concept of time. For thousands of years, devices have been used to measure and keep track of time. The current sexagesimal system of time measurement dates to approximately 2000 BC from the Sumerians. The Ancient Egyptians divided the day into two 12-hour periods, and used large obelisks to track the movement of the sun.

Time Game Telling Time Game - Telling Time is an interactive applet that helps students learn to tell time using the analogue clock. Students practice telling time with time increments of hourly, half an hour, quarter an hr, 5 min increments by looking at an analog clock and then selecting the digital time. Telling time is helpful for kindergartners, first and second graders. students can experiment with telling time. This is a Java applet game.

- The meter. measures the time between those two events, and converts this to a distance. The formulais simple: Distance = ä. (Speed x Time). However the speed of light is 300,000 km per second, so to resolve differences of (say) 1 cm, the meter. must measure time intervals of the order of billionths of a second.

- 3. Use a micrometer to make measurements nearest 10 -6 meters using a micrometer. 4. Use an electric scale to measure mass to the nearest 1/100 of a gram. 5. Use a pendulum to measure the acceleration due to gravity. Introduction Physics is a quantitative experimental science and as such is largely a science of measurement.

Time in physics Main article: History of science. In order to measure time, one can record the number of occurrences (events) of some periodic phenomenon. The regular recurrences of the seasons, the motions of the sun, moon and stars were noted and tabulated for millennia, before the laws of physics were formulated.

Hour The term hora was used to indicate an hour. The time was measured based on the length of the shadow at day time. A hora translated to 2.5 pe. There are 60 pe per day, 60 minutes per pe and 60 kshana (snap of a finger or instant) per minute.

- There are various methods that scientists use to measure distances in space. Using miles or kilometers would require using such large numbers that we would not be able to understand it. The astronomical unit (AU) and the light year (l.y.) are very useful methods. Click on the links to learn what each of these means. Lets examine how long it would take to get to other areas of our universe.

Clock Analog clocks usually indicate time using angles. The most common clock face uses a fixed numbered dial or dials and moving hand or hands. It usually has a circular scale of 12 hours, which can also serve as a scale of 60 minutes, and 60 seconds if the clock has a second hand.

Time in physics Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields.

- Sociolinguistically and linguistically, EFL (English as a Foreign Language) and ESL (Englishas a Second Language) characteristically get measured by their varied deviations against thesupposed constant of ENL (English as a Native Language). In terms of the shift from ENL,EFL is seen as situated a step further than ESL.

- Measure gravitational mass. You can measure mass using a balance. A balance is different from a scale because it uses a known mass to measure the unknown mass whereas a scale actually measures weight. 1  Finding mass with a triple-beam balance or a double-pan balance is a form of measuring gravitational mass.

How to read a tachymeter watch bezel A tachymeter is simply a means of converting elapsed time in seconds per unit to units per hour. A tachymeter-equipped watch can be used to measure distance by timing the travel over the distance while the speed is held constant.

How Do Scientists Measure Earth Age? How Do Scientists Measure Earth Age? Generally speaking, scientists have developed four different methods of determining the age of the earth. By using these methods, or a combination of them, the age of geological formations created by past events and even the fossilized bones of prehistoric animals can be determined.

Why Measure Different quantities (weight, length, area, volume, angle, temperature, speed, time) need different units. And the world has established many commonly accepted units for measuring. Who: Who measures anyway, you ask. Practically everyone and all the time is the answer. Think about how we measure time.
