Universal law of gravitation

The Stokes’ Law was discovered by Sir George Gabriel Stokes. He was an English scientist. Stokes’ Law is a mathematical equation that was derived to calculate the drag force. Stokes’ Law states that the force acting on a particle sinks the particle in the fluid medium under the influence of gravity. The force is directly […]

Ever wonder why a golf ball falls faster than a beach ball? The terminal velocity explains the concept that an object with a smaller cross-sectional area falls faster than the object with a low cross-sectional area. Terminal velocity of the object is the highest velocity it gains when it is falling through a fluid (gas

This article introduces you to the concepts of the centre of mass and centre of gravity of a thin uniform rod. The centre of mass is the point where the entire mass of a system of particles or a rigid body is distributed uniformly. Hypothetically, it is the point where the entire mass of the

There are a number of different forces that act in our surroundings. In simple words, a force can be defined as a pull or push on any object. Force refers to the external agent that has the potential to change the state of motion or the state of the rest of an object. It is

A gravitational field applies the gravitational force on any object which has mass. The mass of the matter causes the gravitational force. If there is a mass, it will apply pressure on another object containing mass. These two masses don’t come in contact but are at a certain distance. Even after that, the second mass

Gravity is one of the fundamental forces in the universe, alongside electromagnetism and the strong and weak nuclear forces. But over time, gravity has been a sort of puzzle for scientists. Ancient scholars and physicists who tried describing the world came up with their explanations as to why things towards the ground. Sir Isaac Newton

The force field that exists in space surrounding any mass or combination of masses is known as a gravitational field. This field spreads in all directions, but the amplitude of the gravitational pull diminishes as one gets farther away from the object. It is measured in newtons per kilogram (N/kg) units of force per mass.

The term “freefall” refers to when an item descends towards the Earth due to the Earth’s gravitational force. Previously, it was assumed that lighter bodies would fall slowly while heavier bodies would fall quickly. For example, if a feather and a metal coin were dropped from the same height, the metal coin would reach the

When an item falls towards the earth due to the gravitational force of the earth, it is referred to as freefall. Previously, it was assumed that lighter bodies would fall slowly while heavier bodies would fall quickly. For example, if a feather and a metal coin were dropped from the same height, the metal coin

A space elevator is a hypothetical structure for transporting materials from a surface of a celestial object through space. The term is most commonly used to describe a structure that extends from the Earth to the geostationary orbit. Beanstalks, sky bridges, space elevators, space staircases, skyhooks, orbit towers, and orbital elevators are all names for
