【 摘 要 】

Newton's laws can represent in the language of verbal, mathematical, physical, and visual. Students who understood concept would express the concepts in various representations consistently. In this research, a mathematical presentation used to reveal the student's concept understanding about Newton first law. The results showed that 21.87% of the students changed the mathematical presentation of Newton's first law (∑ F+=0) into verbal representation incorrectly. Changing the mathematical form of Newton's first law into the form of (0= ∑ F+) caused the percentage of students who did not respond increased, further concluded that "zero intuition" in the equation of Newton first law caused misconceptions.
