Physical quantity Physical quantity is a process of comparing the quantities with a standard reference its also measured in specific units its classified as fundamental and derived quantities. Fundamental quantities do no depend on other physical quantities and derived quantities depend on the fundamental quantities. Scalar quantity has only magnitude but vector quantity involves both magnitude and direction Displacement always deals with shortest ways Velocity is the speed along with direction Velocity equals. Displacement by time. And the acceleration is the change in velocity by time. To find the change in velocity you first find the initial speed and the final speed. then you use the minus the final speed by the initial speed. Force equals mass times acceleration Density equals mass by volume To covert grams into kilograms, you must first divide grams by 1000 to be kilograms.
