EXPLORATION OF THE CONNECTION OF ETA PHYSICAL COGNITION MODEL BETWEEN UNIVERSITY AND MIDDLE SCHOOL-TEACHING EXPLORATION OF POLAR COORDINATE SYSTEMS

Based on the ETA physical cognition model, this paper explores the connection between large and medium schools in physics teaching. Starting from the potential implicit problems in early student cognition, it analyzes examples of centripetal acceleration in circular motion within high school classes, transitioning to the case of elliptical motion in celestial bodies. Mainly from the perspective of establishing axiomatic cognition, this paper explores the connection between velocity and acceleration in polar reference frames.
