While Newton’s principles of motion may appear simple to us now, they were revolutionary centuries ago. The laws of motion explain how things behave when… Read More
Humans learn early in life that all material items have a natural tendency to gravitate towards the earth. Anything thrown up falls to the ground,… Read More
A particle moving in a plane can be described by using the coordinates. But often this information is not enough to fully describe the state… Read More
The periods, orbits, and regions of planets and sun are usually the emphasis of Kepler’s Law of planetary motion. In a sun-centered solar system, the… Read More
When work is done by a force on an object. It acquires energy, it can be any form. Energy can take on many forms and… Read More
The value of gravity’s attraction or potential is governed by the distribution of mass within Earth or another celestial body. As noted previously, the distribution… Read More
The energy that an item has stored in it as a result of its location is referred to as Potential Energy. When we think about… Read More
Have you ever noticed how the water is icy, yet the sand is heated while you’re at the beach? Why is there such a variation… Read More
When often asked, how does an airplane generate lift or how the really cool paint-spray guns work, the most common answer is the Bernoulli’s Principle… Read More
The word science comes from a Latin verb, Scientia. All the natural phenomena in the universe are governed by a systematic understanding known as Science.… Read More
It is essential to know how to describe the motion of a body or a particle. These conventions and methods allow us to formalize and… Read More
Question 11. Find the equation of the ellipse whose foci are at (±3, 0) and which passes through (4, 1). Solution: Let the equation of… Read More
Consider extended bodies to be rigid bodies, and you can solve a lot of problems with them. A rigid body is one that has a… Read More
Question 1. Find the equation of the ellipse whose focus is (1,–2) and directrix is 3x – 2y + 5 = 0, and eccentricity is… Read More
When we apply force to a material, we know that it either expands or compresses in response. The force applied per unit area is known… Read More
