The topic of the study is the effects of mother tongue in the study of Physics Education in secondary school in Enugu North Local Government Area of Enugu State. The aim is to know how the mother tongue affects the learning of Physics Education in Secondary school especially in four selected schools in Enugu North Local Government Area of Enugu State. The targeted population for the study was 500 but collection was questionnaires. The questionnaires were distributed to the four schools selected in Enugu North Local Government Area of Enugu State. The data were analyzed using percentage. The following were the researchers findings. That teachers of Physics Education in Enugu North do not have teaching aids in their various school visited. That students are hardly fluent in Physics Education. That most of the Physics Education teachers are not qualified that students are hardly buy books in Physics Education. That most student are very poor in understanding some of the Physics Education vocabularies. In view of the above, the researcher recommends that teachers should be made to make use of correct teaching method in teaching of Physics that mother tongue should be restricted as stipulated by the national policy on education 4th edition. That student should be taught and made to experiment on Physics always. That teachers of the Physics Education should be made to ensure that at least every student is carried along in the classroom lesson. That qualified teachers should be employed.
