Newton’s laws of motion

Have you ever tried to balance the seesaws in the park? Or try to balance a book by your palm. All these phenomena in physics are examples of equilibrium. In a simple sense, where there is a balance between objects, they are said to attain equilibrium. In the equilibrium of rigid bodies, rigid bodies refer […]

When you travel in a bus or a car, your body is in motion, in the direction of the moving bus. When the driver hits the brakes suddenly, your upper body moves forward with a jerk while your lower body remains in its original position. This happens due to a phenomenon known as inertia. Inertia

In physics, the terms force, speed, velocity, and work are commonly employed, and these variables are classified as scalar or vector. A scalar quantity is a physical quantity with just magnitudes, such as mass or electric charge. A physical quantity possessing both magnitude and direction, such as force or weight, is referred to as a

A rigid body is a form of an ideal example where the body is subjected to no deformities at all. Also, it cannot change its shape or size. One more property of a rigid body is that if two mass particles exist in a closed system, the distance between them remains unchanged during their motion. 

The Reynolds theorem or Reynolds transport theorem (also known as the Leibniz-Reynolds transport theorem) is the generalised form of the Leibniz integral rule in three dimensions. The name is given as such because of Osborne Reynolds. The Reynolds transport theorem states that the sum of the rate of change of property per unit time for

When objects move in a non-stationary frame about another observer, we encounter circumstances. A boat, for example, travels down a river at a given speed, or an aeroplane travels through the air while facing the wind. In all of these circumstances, the effect of the medium on the item must be considered to characterise the

The idea of relative speed is used to compare the speeds of two or more bodies travelling at different rates. To simplify things, one body can be made stationary (i.e. Speed = 0), and the speed of the other body in relation to the stationary body can be calculated as the total of the speeds

Introduction The stationary pressure acts perpendicular to any surface which is in contact with fluid. Pascal found that the pressure at a point for a stationary fluid is the same across all planes which passes through that point in that fluid. Pascal’s law is considered as Pascal’s principle or principle of transmission of fluid pressure.

Physics encompasses understanding the workings of the universe. Physics covers all kinds of movements, from our physical actions to the earth’s movement. The concept of the moment of inertia, governed by its two main principles, explains the various movements occurring in the universe. The two principles are the parallel axis theorem and the perpendicular axis

Introduction: Force constant is an alternative term for a spring constant, as defined by Hooke’s law. This law is a law of physics and is defined as the force required for the extension or compression of a spring by a distance x, varies directly (linearly) concerning that distance, that is, Fs = kx, where k
