Vector and Scalar Quantity

Image
Vector and Scalar Quantity Physical quantities are two types ￫🏇 Scalar Quantity Vector Quantity Scalar Quantities There are some physical quantities which have only magnitude, they do not have any direction. For example mass, distance, time, speed, pressure, volume, work, energy, power, charge, electric-current, temperature, specific heat, etc. These types of Quantities are called Scalar Quantities. Certain Scalar quantities are completely described by a numerical values or by single physical quantity and there addition, subtraction, multiplication, and division according to a ordinary rules of algebra. For example If two bodies having of mass 300 kg and the other having a mass of 150 kg, then the result according to a ordinary rules of algebra is 450 kg. Vector Quantities There are some physical quantities which have magnitude along with direction and which follow Vector rule of addition(vector are added by geometrical rules) are called Vector Quantities ...

Motion | One Dimension Motion (Straight Line Motion)

Motion Frame of reference If we need a co-ordination to determine the speed or position of a particle and its motion, from which the coordinates of particle or object (x,y,z) express the position of motion or particle relative to the original point. In such co-ordination Frames, there should also be a system to measure time, for which the position of object can be unique evaluated on different moments. Such instruction frames are called space-time co-ordinate frames. Generally there are two types of co-ordinates frames, Inertial and non-inertial. Inertial co-ordinate   Inertial co-ordinate system are those co-ordinate system in which they follow Newton's law. In other words those Co-ordinate system which are in motion or in rest they all are in absolute velocity are called Inertial co-ordinate system. Non Inertial co-ordinate Non Inertial Co-ordinate System are such co-ordinate system in which they do not follow Newton's law. Rest and Motion What is Motion? Wi...
