Physics is a science that deals with matter and energy, and their interaction. The subject matter of Physics includes mechanics, heat, light, optics, electricity, magnetism, radiation, gravitation, atom structure etc. Physics concepts are included in the science textbook form primary level of education. Some Physics abstract concepts are difficult to comprehend for Primary and Secondary students. The complex and abstract nature of many concepts in physics makes them difficult to understand. It results into that the Physics subject become much more difficult due to the presence of varied misconceptions in students. The aim of the study is to identify the Physics misconceptions related to gravity, motion and inertia concepts among secondary school students. The study was descriptive in nature. One hundred forty (N=140) Ninth standard semi-english secondary school students of Kolhapur city were selected by purposive sampling method. The researchers identify three concepts of Physics i.e. Gravity, Motion, Inertia. The tool was constructed and data was collected from the Ninth standard students of affiliated to State Board of Kolhapur city. The misconceptions found were 'gravitational force just act on only heavy object', 'gravity does not affect the object in water', 'a continuous force is needed for continuous motion', 'speed and motion are same and 'inertia is the force that keep objects in motion' among the students.
