{"knowledge_schema": {"broad_category": "Physics \u2192 Mechanics \u2192 Relativistic Kinematics", "refinement": "This problem specifically deals with the kinetic energy of particles moving at relativistic speeds, which requires the use of relativistic equations rather than classical mechanics.", "specific_scope": "The focus is on calculating the kinetic energy of a proton moving at 0.98 times the speed of light (0.98c) in a particle accelerator, using the relativistic kinetic energy formula.", "goal": "Calculate the kinetic energy of the proton to determine its energy in electron volts (GeV) at relativistic speeds."}, "summary": "This problem falls under the category of physics, specifically in the realm of relativistic mechanics, where we calculate the kinetic energy of a particle moving at a significant fraction of the speed of light. The scenario involves a proton moving at 0.98c, and the goal is to use the appropriate relativistic formulas to find its kinetic energy in GeV. The answer provided is 3.67 GeV, which reflects the energy associated with the proton's high-speed motion."}
