Current technological developments have been widely used in physics research, such as the use of tracker programs used to analyze videos. This is very useful when studying or analyzing motion. This study aims to design physics practicums (momentum and collisions) by analyzing position, speed, and time using video analysis Tracker to improve students' ability in interpreting graphics. The method used in this research is the experimental method. The technique of collecting data uses tracking video using video analysis. The results of this study indicate that the momentum practicum design developed can be used to improve students' ability to interpret graphs. Other physical phenomena can also be analyzed using video analysis Tracker. 1. Introduction The concept of momentum and collision is very easy to find in everyday life. For example, a heavy truck has greater momentum than a light car that moves at the same speed [1], then a billiard ball collides, collides a baseball with a bat. In physics, there are two kinds of momentum, namely linear momentum (p) and angular momentum (L). In this study only linear momentum will be discussed. The momentum of a particle is explained as a multiplication between the mass of matter and velocity. Therefore, every moving object has momentum. Mathematically, linear momentum is written as follows: p = m v (1) p is momentum (vector quantity), m mass (scalar quantity) and v speed (vector quantity). One application of momentum conservation law is in the event of collisions of two objects. In a collision always involve at least two objects. Collisions are divided into three types, which are perfectly resilient collisions, collisions are not resilient at all, and partially resilient collisions. In accordance with the conservation law of energy, conservation law also applies to momentum where the momentum of objects before and after collisions is the same. Therefore, it can be concluded that: in the event of a collision, the amount of momentum of objects before and after the collision remains as long as there is no external force acting on these objects. Mathematically for two colliding objects can be written: p A + p B = p A ’+ p B ’ or m A v A + m B v B = m A v A ’ + m B v B ’ (2) While the magnitude of the coefficient of restitution ( e) for all types of collisions applies:
