Data collected by using test NGCI (Newtonian Gravity Concept Inventory), CRI (Certainty of Response Index), and Interview to discribed types of conceptual understanding students'. Analysis methods data used Descriptive qualitative technique. Based on the analysis CRI, this research find 28,51 % student understand the concept, 4,68 % understand the concept but not sure , 27,9% misconception, and 25,62 % not understand the concept. The most misconception occurs in sub concept the relations of mass to the gravitational force that is 49,65 %. This research can be used for basic research increase student conceptual understanding.This is an open access article distributed under the Creative Commons 4.0 Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.
