The present work has as main objective to awaken in students an interest in physics and its natural phenomena, so that the student may be more curious to observe his daily life, and associate physics with his life. Newton's laws are very present in our daily lives, since they address the concepts of force and mass. Every day we observe several types of movement: MRU, MRUV, MCU and etc., movements that change from moment to moment. These changes in movement are determined by the resulting force and the mass of the bodies, thus generating an acceleration. The physical law responsible for explaining such a phenomenon is Newton's second law. In order to carry out this work, a questionnaire will be applied to the 3 year class of high school at the Centro de Ensino Josélia Ramos de Almeida, in São João dos Patos - Maranhão. Students will observe all physical phenomena during their routine, within a week. And then they will associate which phenomena are related to Newton's second law, thus being able to understand that the explanations for many activities performed, many phenomena that occur and are part of their daily life can be explained by physics. The results obtained were satisfactory, as the students embraced the work and were very interested in participating in it. They were able to see the physics around them, they could prove that physics is really part of their daily lives.
