The idea of work as a form of energy transfer dates back to ancient times, but it wasn’t until the 17th and 18th centuries that the concept began to take a more scientific form. Aspects of the concept of work done appear as early as 60 AD in the writings of Hero of Alexandria. He … Read more
The story begins with the early astronomers who noticed the circular paths of stars and planets in the sky. They believed that celestial bodies moved in perfect circles, which was the accepted truth for many centuries. The Greek philosopher Aristotle proposed that the Earth was stationary and everything in the heavens revolved around it in … Read more
The concept of force has been a part of human curiosity for centuries. The modern understanding of forces in mechanics largely stems from the work of Sir Isaac Newton, who, in the 17th century, formulated the three laws of motion that describe how objects interact with forces. These laws laid the foundation for classical mechanics, … Read more
The concept of equilibrium in mechanics has been around since the time of Aristotle, but it was Isaac Newton who brought it into the realm of physics with his laws of motion. The idea is rooted in the search for conditions under which objects can exist in a state of balance or rest. The concept … Read more
The concept of momentum conservation has been around since the time of Galileo, but it was Isaac Newton who formalized it in his laws of motion. It’s a principle that has stood the test of time and countless experiments. The story begins with early philosophers and scientists trying to understand motion. Aristotle had his ideas … Read more
The Law of Inertia, often referred to as Newton’s First Law of Motion, has a fascinating history that spans several centuries and involves a series of discoveries and refinements. Initially, the Greek philosopher Aristotle believed that an external force was necessary to maintain an object in motion. This view was widely accepted until the Renaissance … Read more
The story of uniform circular motion begins with the ancient Greeks. Aristotle was one of the first to observe that celestial bodies like the stars and planets moved in what seemed to be perfect circles in the sky. He believed that the heavens were perfect and unchanging, and thus the circular motion was the most … Read more
Long ago, people observed objects flying through the air, whether it was a rock thrown by hand or an arrow shot from a bow, but they didn’t understand the forces at work. The first significant thoughts on motion came from Aristotle in ancient Greece. He believed that an object moves because a force is acting … Read more
The concept of motion in a plane, or two-dimensional motion, has been a subject of fascination and study for centuries. It encompasses the movement of objects in a plane, considering both the x-axis and y-axis, unlike one-dimensional motion which only considers a single line of action. In ancient times, Aristotle’s view dominated, suggesting that objects … Read more
The concepts of scalars and vectors are deeply rooted in the history of mathematics and physics. They are essential tools that scientists and mathematicians use to describe the world around us. Scalars have been around since the early days of algebra, where simple numbers represented quantities like distance, mass, and time. These are quantities that … Read more
