UFPR 2ª Fase 2026 Questão 07

🚀📚 UFPR 2026 – 2nd Phase: The question that mixes Dynamics, Friction, and Energy in a single problem! If you want to do well on the UFPR essay exam, you need to master the art of transforming forces into equations and energy into physical arguments. 💡 In this question, a block moves up an inclined plane at a constant speed, while friction tries to impede its movement. The mission is to discover: 🎯 What is the expression for the force F that keeps the block moving upwards? 🎯 What is the change in gravitational potential energy when it reaches the top of the plane? ⚠️ Attention: constant speed means zero acceleration, but this does not mean that there are no forces acting! 💬 Before watching the solution, answer in the comments: 👉 Can you identify all the forces acting on the block? 👉 Does friction help or hinder the movement? 👉 Does height H influence the force needed to go up? 📖 In this lesson, we solve it step by step using: ✅ Decomposition of weight on an inclined plane ✅ Kinetic friction force ✅ Newton's 2nd Law ✅ Gravitational Potential Energy 🔥 Perfect question for those preparing for the second phase of the UFPR exam and wanting to learn how to justify each step of the solution as required by the exam board. 👍 If the content helps with your studies, leave a like and share it with that friend who is in the final stretch before the entrance exam! #UFPR2026 #SecondPhaseUFPR #UFPREntranceExam #UFPRPhysics #InclinedPlane #Friction #Dynamics #PotentialEnergy #MechanicalEnergy #PhysicsEntranceExam #EntranceExam #ExactSciences #PhysicsTeacher 🔔 Don't forget to subscribe to the channel and activate notifications! ❓ Have questions about Physics?
