Context: The Tracker software is widely used in physics education to measure kinematic quantities such as position, velocity, and acceleration through video analysis. Its application allows students to observe and quantify the behavior of objects in various experiments. However, its use in dynamics is less common because it does not directly measure key quantities such as forces or energy. Objective: The objective of this study was to determine the friction coefficient between a block sliding down an inclined plane, using Tracker and Newton's laws. Method: A low-cost experiment was conducted where a block was released from the top of an inclined plane. The movement was recorded using a mobile phone, and the position and velocity graphs and equations were analyzed with Tracker. Subsequently, by applying Newton's second law, the friction coefficient was determined. Results: The analysis revealed that the block descended with an acceleration of 2.54 m/s² and a kinetic friction coefficient of 0.44 was determined. Conclusions: This study highlights the importance of incorporating technological tools in physics education, facilitating practical learning and the development of critical skills with accessible resources.
