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.. mr. taylor. 8.6.

Momentum = Mass x Velocity. p. =. mv. The SI unit for momentum is . kg·m. /s. Momentum and velocity are in the same . direction. Is a vector. Using the equation. p=. mv. At the same velocity, as mass increases – momentum increases. Momentum = Mass x Velocity. p. =. mv. The SI unit for momentum is . kg·m. /s. Momentum and velocity are in the same . direction. Is a vector. Using the equation. p=. mv. At the same velocity, as mass increases – momentum increases. What factors affected how fast objects move after a collision? (Think of your lab). Section 1: Momentum and . Impulse. Linear Momentum:. Momentum is defined as . mass times velocity. .. Momentum is represented by the symbol p, and is a . Shyamnath Gollakota. Dina Katabi.
