Many people in this world really underestimate how physics contributes to our daily lives whether be walking, talking, or any other action. Many equations, graphs, and a little bit of math help us understand what goes on behind the curtain. Physics also have shared relations with science and combining those physics to other types of studies. To understand physics, we need to discuss the laws of motion which are called the Newton’s Laws of Motion, there are only three. According...

In 1687 Isaac Newton presented the three laws of motion. These laws created a massive advancement into the Age of Enlightenment and the Industrial Revolution. The laws were taken very seriously and not many questioned them, since it was science. Fast forward to the modern day, behavioural laws have been introduced and people question and go up against every aspect of it. Like Isaac Newton’s laws, there are also three laws of human behaviour. These laws, although quite similar, have...

By its formal definition, light pollution means the superfluous, unwanted, or poor use of manufactured light during nighttime. Other aliases include photopollution and luminous pollution. This is correct, by all means, but is inadequate in such a way that it doesn’t speak for all the parts that go into light pollution. In other words, light pollution is much more than that. More often than not, this specific type of pollution is overlooked. Light pollution effects are often ignored and aren’t...

Air we breathe in consists of molecules. Even the tiniest of regions of air will contain millions and millions of molecules. These molecules are in constant motion, traveling randomly and at great speed. There is a constant bombardment with each other and every other object that is in contact with the air. One interesting thing about air is that it is a medium through which heat or sound travels. But our current main attention will be on sound. Sound is...

Introduction: This report investigates the effect of wheels on the speed of a solar car. This is achieved by considering the effects of force and energy transformation and what happens if extra wheels are added. Force is the act of pushing or pulling on an object with mass that causes it to change velocity (e.g.: accelerating a car). Force is also a vector which means it has both magnitude and direction. Energy transformation aka energy conversion is the act of...
