The commutative property of vector addition. The associative property of vector addition. Additive identity of vectors. Additive Inverse of a Vector. What is a vector in physics? A vector is a quantity or phenomenon that has two independent properties: magnitude and direction. The term also denotes the mathematical or geometrical representation of such a quantity. … Read more
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector. What is speed in physics and its unit? Speed is defined as the rate of change of … Read more
Motion is a change in position of an object over time. Motion is described in terms of displacement, distance, velocity, acceleration, time and speed. What is motion in physics explain? motion, in physics, change with time of the position or orientation of a body. Motion along a line or a curve is called translation. Motion … Read more
Wavelets are wave-like oscillation with an amplitude that begins at zero, increases, and then decreases back to zero. What is wavelet used for? The wavelet transform (WT) can be used to analyze signals in time–frequency space and reduce noise, while retaining the important components in the original signals. In the past 20 years, WT has … Read more

Introduction Computational physics has been an important research tool in physics for over 40 years. It has enabled physicists to understand complex problems more completely compared to using theoretical and experimental methods alone. What is meant by computational physics? Computational physics is the study of scientific problems using computational methods; it combines computer science, physics … Read more
In physics, a moment is a mathematical expression involving the product of a distance and physical quantity. Moments are usually defined with respect to a fixed reference point and refer to physical quantities located some distance from the reference point. What is moment explain with example? In physics, a moment can be visualized as the … Read more
In Physics, force is defined as: The push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body’s state of rest or motion. It has a magnitude and a direction. What is called a force? A force is a push or pull … Read more
An obvious, very important motivation for the study of Solid State Physics is the fact that the microscopic properties it deals with are responsible for the majority of modern technology. These properties determine the mechanical strength of materials, how they interact with light, how they conduct electricity, etc. What is meant by solid state physics? … Read more
momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on the particle. What is the simple definition of momentum? : … Read more
