What is a Pendulum?
Body suspended from a fixed point to act as a pendulum that swings back and forth as a result of gravity. Because the period—the amount of time between each full oscillation—is constant, pendulums are employed to control the movement of clocks.
By contrasting the motion of a swinging lantern in a cathedral in Pisa with his heart beat, the Italian scientist Galileo first discovered the consistency of a pendulum's period. In 1656, Christiaan Huygens, a Dutch mathematician and physicist, created the first pendulum-driven clock.
Huygens invented a pivot that let the suspended body, or bob, swing along a cycloid rather than a circle, which solved the crucial challenge of having the period of a pendulum genuinely constant. Galileo and Huygens have been given different credit for the development of the pendulum clock.
What are backyards?
Backyards are widespread in Western suburban projects and are often referred to as rear gardens or plain gardens in the UK.
Up to the middle of the 20th century, a property's rear yard in Australia would often include a chicken run, an outhouse, a vegetable patch, and a woodpile. More lately, outdoor activities like a barbecue and swimming pool have taken their place. However, since the 1990s, Backyards have been disappearing in Australian suburban development as homes increasingly take up nearly the entire building plot.
