Scalar and vector quantities: A scalar quantity is a one dimensional measurement of a quantity, like temperature, or weight. A vector has more than one number associated with it. A simple example is velocity. It has a magnitude, called speed,To know more about Scalar and vector quantities Video,watch Scalar and vector quantities Video to learn more . Scalars and Vectors: Scalars have magnitude only. […]

Speed Video : The rate of change in distance with respect to time. Since speed is built from distance, a scalar quantity, then speed is also a scalar quantity. This means it carries no direction information with it.To know more about Speed ,watch Speed Video to learn more . Speed: Nearly everyone knows that […]

Types of Graphs Pie Graph A pie graph, also known as a pie chart, is a type of graph commonly used in conjunction […]

Introduction About Velocity Video: The speed of a moving object in particular direction is called velocity. Velocity has both magnitude and direction while speed has only magnitude and no direction.watch Introduction About Velocity Video to learn more. Velocity of an object is the distance covered in particular direction in unit time. Velocity: Velocity is a vector expression of […]

Uniform Motion and Non Uniform Motion: Uniform Motion:- A body is said to have a uniform motion if it travels equal distances in equal intervals of time, no matter how small these intervals may be.A distance-Time graph for uniform motion is a straight line. Non-Uniform Motion:- A body is said to have a non- uniform motion […]

Introduction About Uniform Circular Motion : Uniform circular motion is the motion of an object traveling at a constant speed on a circular path Uniform circular motion: When an object is experiencing uniform circular motion, it is traveling in a circular path at a constant speed. If r is the radius of the path, and we define the period, T, […]

Introduction About Displacement and Distance: Distance and displacement are two quantities that may seem to mean the same thing yet have distinctly different definitions and meanings.watch Introduction About Displacement and Distance to learn more. Distance is a scalar quantity that refers to “how much ground an object has covered” during its motion. Displacement is a vector quantity that refers to […]

Introduction About Equations of Motion: One obvious way to improve on the Rouse chain, is by introducing hydrodynamic interactions between the beads. The chain so defined is called the Zimm chain . The equations describing hydrodynamic interactions.watch Introduction About Equations of Motion to learn more. Equations of Motion: In studying the motion of objects it is often helpful […]

Motion of Living and Non Living Things: Living and nonliving things alike are composed of elements. However, there are major differences between a nonliving object and a living organism. To understand what makes a living thing alive, you need to look at the common characteristics that define all life. Although a blade of grass and […]

Introduction About Rest on Motion: A body does not change its position with respect to its surroundings then. the body is said to be in a state of rest.” MOTION. “If a body continuously changes its position with respect to its surrounding. than it is said to be in a state of motion.watch Introduction About Rest on Motion to […]

Introduction About Acceleration Videos: Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.watch Introduction About Acceleration Videos to learn more. Acceleration is defined as the rate of change of velocity. Acceleration is inherently a vector quantity, and an object will have […]
