This laboratory work is a fundamental part of the 7th-grade physics curriculum, designed to help students understand how friction operates in the real world through hands-on measurement. Laboratory Work №3: Study of Friction Force
Pull the block across different surfaces (e.g., glass vs. sandpaper) while keeping the weight constant.
