PPT-Conservation of Momentum and collisions

Law of Conservation of Momentum With no external force momentum doesnt change Its the opposite of the impulse momentum relationship Ft Δmv Example Consider a gun being fired A gun recoils when it is fired . http://. www.aplusphysics.com. /courses/honors/momentum/. collisions.html. Unit #4 Momentum. Objectives and Learning Targets. Define and calculate the momentum of an object.. Determine the impulse given to 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. We will now quantify exactly how it hits the fan.. Momentum. Momentum = product of mass X velocity. Symbol for momentum is “p” (don’t ask me why). So, p = . mv. Momentum is also a vector and points in the direction of velocity. Chapter 7. 7.1 The Impulse-Momentum Theorem. This section deals with time-varying forces affecting the motion of objects. . The effects of these forces will be discussed using the concepts of . i. mpulse and linear momentum.. & 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:. . Chapter 9. Copyright © 2014 John Wiley & Sons, Inc. All rights reserved.. 9-1. Center of Mass.

When . dealing with collisions in 2-dimensions it is important to remember that momentum is a vector with . magnitude. and . direction. . . When . finding the . total momentum. , we have to do . vector addition. 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. Collisions . of. . Point . . Masses . in Two Dimensions. . Boom .

Momentum. – tendency of objects to keep going in the same direction with the same speed. Depends on mass and velocity. Has direction. The momentum of a ball depends on its mass and velocity. Ball B has more momentum than ball A. & 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:. . 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. By Jonathan. Recap:. 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 . 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. .
