Warm Up. Review HW from 7.1. Practice Problems for 7.2. Intro to Collisions (7.3). Tomorrow . Conservation of Momentum Lab. Thursday: . Review HW from 7.2. & Energy in Collisions. Given some information, & using conservation laws, we can determine a . LOT. about collisions without knowing the collision forces! To analyze . ALL. collisions:. . Completely elastic collision. If . all. of the kinetic energy is conserved, the collision is . completely elastic.. Completely inelastic collision. If the objects . stick together. , the collision is . Momentum & Collisions. Momentum and Collisions. Momentum is a quantity of motion that depends on both the mass and velocity of the object in question:. Remember. : Momentum is a _______________ quantity, with the same sign as its velocity. As with any vector you can assign any direction as positive and the opposite as negative, but as convention we will refer to . Bell Ringer. A . 40 kg . miniature horse runs west at . 8m/s. . What is the force . of impact if it hits a wall and . comes to a stop . in . 0.5s. ?. Objectives. We will . demonstrate . and apply the laws of . Inelastic vs. Elastic. Pg. 233 – 239. Pg. 240 - 248. Momentum vs. Energy. All interactions conserve momentum.. They do . not necessarily. conserve kinetic energy.. Obvious example: Explosions. Kinetic energy before is zero.. University of Michigan. Physics Department. Mechanics and Sound . Intro . Labs. Two-Dimensional Collisions. You have now seen the laws of conservation of momentum and energy in action in one-dimensional collisions, and you have begun to explore rotational motion. Now it is time for you to apply these concepts to a two-dimensional situation.. The truth about …. The only way to tell …. … whether a collision is elastic or inelastic is to find out whether . kinetic energy . is conserved or not.. You have to calculate the kinetic energy before and after the collision.. & Energy in Collisions. Given some information, & using conservation laws, we can determine a .
