If the value of g suddenly becomes……………….. = When the value of gravity doubles, the weight of the object, which is the force pulling it toward the ground, also doubles. This increased weight creates a stronger force pressing the object onto the floor. The force of friction between the object and the floor is directly … Read more
A stone thrown vertically upwards ……… = To prove that the time taken to reach the maximum height (going up) is equal to the time taken to return to the starting point (coming down) for a stone thrown vertically upwards, we can use some basic kinematic equations. Let’s consider the motion of the stone. The … Read more
three laws given by Kepler : Kepler’s Three Laws of Planetary Motion are: Kepler’s First Law (Law of Ellipses) : Planets move in elliptical orbits with the Sun at one focus of the ellipse. Kepler’s Second Law (Law of Equal Areas): An imaginary line drawn from a planet to the Sun sweeps out equal areas … Read more
(i) Free Fall: – Definition: Free fall refers to the motion of an object under the sole influence of gravity, where the only force acting on the object is gravity itself. In free fall, the object is subject to acceleration due to gravity, and it falls without any other forces, such as air resistance, acting … Read more
What is the difference between mass and weight : Before delving into the differences between mass and weight, it’s important to establish a clear understanding of these fundamental concepts in physics. Both mass and weight are crucial when describing and analyzing the behavior of objects in the physical world. While they are often used interchangeably … Read more
Force and motion : Are fundamental concepts in physics that describe how objects move and interact with each other. Let’s break down these concepts. Force : Motion : In summary, the relationship between force and motion is described by Newton’s laws of motion, which are fundamental principles in classical physics. These laws explain how the … Read more
Five Definitions of Gravitation : Gravitation, the fundamental force of attraction between objects with mass, is a concept that has captivated human curiosity for centuries. From the groundbreaking insights of Sir Isaac Newton to the revolutionary theories of Albert Einstein, our understanding of gravitation has evolved, revealing its profound role in shaping the cosmos. In … Read more
