What is Physics Physics is the study of our natural world (phenomenon and its interaction)
Like all other sciences, physics is based on experimental observations and quantitative measurements. The main objective of physics is to find the limited number of fundamental laws that govern natural phenomena and to use them to develop theories that can predict the results of future experiments When we carry out our experiments, we need to make accurate measurements in order to obtain reliable results The fundamental laws used in developing theories are expressed in the language of mathematics, the tool that provides a bridge between theory and experiment.
