Law of Inertia

Law of Inertia

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

Uniform Circular Motion

Uniform circular Motion

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

Projectile Motion

Projectile Motion

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

Motion in a Plane

Motion in a Plane

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

Scalars and Vectors

Scalars and Vectors

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

Relative Velocity

Relative Velocity

The concept of relative velocity is deeply rooted in the history of physics and our understanding of motion. It’s a concept that has evolved, influenced by the work of many great scientists. Galileo Galilei was one of the first to discuss the idea of relativity in motion. He proposed that motion is relative — meaning … Read more

Kinematic Equations for Uniformly Accelerated Motion

Kinematic Equations

The story of kinematic equations begins in ancient times with the need to understand the motion of celestial bodies. Early astronomers and mathematicians observed the stars and planets, trying to predict their movements. This curiosity laid the groundwork for the field of kinematics. Kinematics is a term derived from the Greek word “kinesis,” meaning motion. … Read more

Acceleration

Acceleration

The concept of acceleration has been pivotal in physics, dating back to the works of Galileo Galilei and Sir Isaac Newton. Galileo Galilei’s work on acceleration was a significant departure from the prevailing Aristotelian physics of his time. Aristotle claimed that an object’s fall speed depended on its weight and the medium it was falling … Read more
