Position The position is where an object is located in space relative to a reference point. It’s like saying, “I am 5 meters to the right of the tree.” That tree is your reference point. Imagine you’re playing a game of hide and seek. You need to describe where you are without being seen. In … Read more
The concept of a frame of reference is fundamental in physics, and it has evolved as our understanding of the universe has grown. Initially, the idea of a frame of reference wasn’t clearly defined. Ancient astronomers like Ptolemy used Earth as the central point (geocentric model) to explain the motion of celestial bodies. Later, Copernicus … Read more
Gravitational Field due to a Point mass Suppose a particle of mass M is placed at point O and a second particle of mass m is placed at point A. Let OA = r. The mass M creates a field \(\displaystyle \overrightarrow{E} \) at the side of mass m and this field exerts a force … Read more
The gravitational field is a region of space where a mass feels a force due to the presence of another mass. The gravitational potential is a measure of how much energy a mass has at a point in the field. The intensity of the gravitational field, denoted by E, is a measure of the strength … Read more
Gravitational potential is a fundamental concept in the study of gravity, offering a unique perspective on how mass influences the space around it. In physics, gravitational potential is a scalar field that represents the amount of gravitational potential energy per unit mass at a specific point in space. The gravitational potential at a point in … Read more
Gravity is a fundamental force of nature that causes objects with mass to be attracted to each other. Sir Isaac Newton first described gravity in the 17th century through his Universal Law of Gravitation, and it remains a cornerstone in our understanding of physics. Gravity, a fundamental force woven into the fabric of our universe, … Read more
Introduction The Universal Law of Gravitation, a groundbreaking principle formulated by Sir Isaac Newton (25 December 1642 – 20 March 1726/27) in the 17th century, stands as one of the cornerstones of classical physics and a monumental leap forward in our comprehension of the forces governing the cosmos. Unveiled in Newton’s seminal work “Philosophiae Naturalis … Read more
Introduction Kepler’s Laws of Planetary Motion, formulated by the German mathematician and astronomer Johannes Kepler in the early 17th century, represent a groundbreaking set of principles that revolutionized our understanding of the celestial dance performed by planets in our solar system. These laws laid the foundation for the later development of classical celestial mechanics and … Read more
The story of the Laws of Motion is a fascinating journey through time, beginning with ancient philosophers and culminating in the work of Sir Isaac Newton. The earliest ideas about motion date back to philosophers like Aristotle, who believed that the natural state of objects was to be at rest and that they required a … Read more
