Universal law of gravitation

Gravitational acceleration (symbolized g) is a term that denotes the intensity of a gravitational field. It’s measured in metres per second squared (m/s²). 1 g is approximately 9.8 m/s² at the Earth’s surface. Gravitational acceleration, g, around the greater mass is defined as follows: g = −G M/ r² (where M is the mass of the […]

What does the term “surface tension” mean? It’s a phenomenon where the surface of a liquid behaves like an elastic sheet. When a phenomenon exists between two types of liquids, interface tension occurs. Depending on surface tension values, liquids normally aim to achieve the smallest possible surface area.  A descending drop can take on a

Geopotential is the pressure exerted by a given water weight because of gravity and atmospheric pressure acting upon it. Geopotential can be calculated for any point on the Earth’s surface, given the potential sea level and its height above sea level (elevation) are in metres or feet. The difference between an object’s potential energy at

The pressure is just a scalar quantity that also is defined as force per unit area acting in a perpendicular direction to the surface. Pressure is an important physical quantity that is used in a variety of fields, including thermodynamics, solid mechanics, and fluid mechanics. There are numerous ways to express pressure depending on the

The force that causes objects to fall is known as gravity. Two bodies will be pulled together by gravitation. The universe is filled with forces, but they can’t always be seen. When things move away from the gravitational pull, the effect weakens. Sir Isaac Newton came up with Newton’s law of gravitation in the year

Introduction The centre of mass is defined as the average of spatial arrangement of masses in a system or the distribution of masses in a system. It can also be stated as a point where the mass of a body is concentrated. At this point, the applied force results in a linear acceleration without the

The value of gravitational push is determined by the division of the mass within the earth or any celestial body.  [g means gravity = universal force of attraction residing among every matter present as a part of the universe] Gravity is considered the driving force to keep everything close and bound. Acceleration or movement on

Stress is the measure of force acting on a body per unit of its area to change the body’s volume, length, or shape – the SI. The unit of stress is N/m2 (Newton per square metre). Strain is the measure of the extent to which a body has deviated from its initial condition after the

Ever wondered what are black holes? They were first introduced in the early 1900s by Albert Einstein through his theory of general relativity. His endeavour led to an intense observation and research effort that has continued for over 100 years. Black holes are objects with so much mass that no force in the observable universe

The greatest velocity obtained by a body falling through a fluid is known as terminal velocity. When the total drag and buoyancy equal the downward gravitational force exerted on the item, terminal velocity is noticed. The object’s acceleration is zero since the net force exerted on it is zero. Expression for terminal velocity Let us
