Abstract
<p>Impulse momentum theorem is one of the fundamental principles of physics, especially in mechanics. Therefore, students’ understanding of impulse and momentum will contribute to their success in learning physics. This study exposed common students difficulties in solving problems related to impulse and momentum. The subjects consisted of 175 students of a Senior High School in Malang, 70 students of grade XI who recently learned about impulse and momentum and 105 students of grade XII who relearned the topic for national examination preparation. The data were gathered using multiple-choice test with open explanation and confidence rating scale. The study concluded that the students’ difficulties were not only caused by their lack understanding of the concepts but also by their deficiency in using vectors.</p>

To reach these aims is not as easy as one thinks. It is because students often have mistakenly formed conceptions when they come to physics lessons (Halim et al, 2014) or they have not understood the basic knowledge before they learn new concepts (Turányi & Tóth 2013)
Summary
One of the important goals of learning physics is to facilitate students to grasp fundamental physics concepts and to apply them to solve related physics problems. To reach these aims is not as easy as one thinks. It is because students often have mistakenly formed conceptions when they come to physics lessons (Halim et al, 2014) or they have not understood the basic knowledge before they learn new concepts (Turányi & Tóth 2013). When designing a physics lesson teachers need to be aware to students’ misconceptions and the concepts that students tend to be difficult to understand
