What is Physical Quantitie ?
-The quantities which can be measured is called physical quantities.Length,Breadth,Time,Area,Volume,etc can be measured so it is called 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.
