PPT-Chapter 6 Momentum and Collisions

Momentum and Impulse Objectives 1 Compare the momentum of different moving objects 2 Compare the momentum of the same object moving with different velocities 3 Identify some examples of change in the momentum of an object. Date, Section, Pages, etc.. Mr. Richter. Agenda. Today:. 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. Linear Momentum. Momentum is a measure of how hard it is to stop or turn a moving object.. p. = m. v. (single particle). P . = . Σ. p. i . (system of particles). Problem:. How fast must an electron move to have the same momentum as a proton moving at 300 m/s?. 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 . PlasMA. Nonequilibrium. Dynamics. in Astrophysics and Material Science. YITP, Kyoto, Japan, Oct. 31-Nov. 3, 2011. Tetsufumi. Hirano. Sophia Univ./. the Univ. of Tokyo. Outline. Introduction. Physics of the quark gluon plasma. & 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:. . Notes. Momentum Conservation Principle. One of the most powerful laws in physics is the law of momentum conservation. . For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects . 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. Corina. . Bot. , PhD (NJIT, C. 2. PRISM).

Last week we talked about countersteering. What was . countersteering. ?. Turn in the other direction in order to complete a turn.. A while back we mentioned velocity. What was . Law of Conservation of Momentum. With no external force, momentum doesn’t change. It’s the opposite of the impulse momentum relationship!. Ft = Δmv. Example. Consider a gun being fired.. A gun recoils when it is fired. . Momentum is a quantity defined as the product of the mass and velocity of an object.. Unit of Momentum. The equation illustrates that momentum is directly proportional to an object’s mass and the object’s velocity.. What is Momentum? Unit 8 Section 3 Momentum Momentum is a property of ALL moving objects Momentum is the product of the mass and velocity of an object. Momentum = mass x velocity ( P=M x V) Momentum is labeled as kg x m/s with a direction. Momentum. Measures how hard it is to stop a moving object.. Momentum can be defined as . "mass in motion.". . All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. .
