Question

Answer the following question -:
c) Why were the ancient methods of measuring time abandoned?
d) How do mechanical clocks work ?
e) What is a speedometer?

Answer 1

Answer:

1) Because we had new technology in hand, and everybody forgot our ancient methods of measuring time.

2) The energy is usually stored in a weight or spring. When it is wound, energy is transferred from our muscles and into the driving weight (as it moves up against the force of gravity) or the mainspring (as it tightens up). This energy is released into the timekeeper as the weight drops or the mainspring unwinds.

3) A speedometer or speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the early 20th century, and as standard equipment from about 1910 onwards.

• it is easier to watch time with the help of digital clocks, or just by clock . so people abandoned ancient methods
• The energy is usually stored in a weight or spring. When it is wound, energy is transferred from our muscles and into the driving weight (as it moves up against the force of gravity) or the mainspring (as it tightens up). This energy is released into the timekeeper as the weight drops or the mainspring unwinds.
• Speedometer is a device which indicates speed on the dashboard of the car.
