What is Fundamental Physical Quantity ?
Those physical quantities which are independent of each other are called fundamental physical quantities.There are seven fundamental physical quantities.
Introduction of Velocity and Acceleration (Distance and Displacement)
Distance The distance covered by a moving body is the length of path covered by the body. In SI system, distance is measured in metre (m). It is a scalar quantity as it has only magnitude but no direction. Displacement The shortest distance covered by a moving body in a fixed direction is called displacement. In SI system, it is measured in metre (m). Displacement is a vector quantity as It has both magnitude and direction.
