PPT-MOMENTUM

https wwwyoutubecomwatchvhTZIkpppuw A truck rolling down a hill has more momentum than a roller skate with the same speed But if the truck is at rest and the roller skate moves then the skate has more momentum Moving objects can have a large momentum if it has a large mass a high speed or both. Analogies. Heat .  Mass  . (sometimes). Momentum. Analogies are useful tools. An aid to understand transfer phenomena. A sound means . t. o predict behavior of systems for which limited quantitative data are available. Chapter 3, Section 7. Date:. HW: PTG #1-8, pg. 332. Learning Objective:. Explain collisions in terms of Newton’s Laws, momentum, and impulse. Success Criteria:. Define impulse. Explain conservation of momentum. If a system has . no external forces . acting on it (. eg. no friction), then the system is . isolated.. Total momentum in an isolated system is said to be . conserved. . . A . system. is a pair or group of objects that are interacting in some way.. http://www.aplusphysics.com/courses/honors/momentum/conservation.html. Unit #4 Momentum. Objectives and Learning Targets. Define and calculate the momentum of an object.. Determine the impulse given to an object.. What was Angular Momentum Again?. If a particle is confined to going around a sphere:. At any instant the particle is on a particular circle. r. v. The particle is some distance from the origin, . r. 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?. 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.. P221: November 8, 2013. Summary. Linear momentum. Angular momentum. Clicker Question. A student is riding on the outside edge of a merry-go-round rotating about a frictionless pivot. She holds a heavy ball at rest in her hand. If she releases the ball, the angular velocity of the merry-go-round will:. stratiform. precipitation: Calculations with a high-resolution numerical . model. Yang, M.-J., and R. A. .

An off centre force is referred to as an eccentric force.. Examples of a force being applied outside the centre of mass of an object or body to cause rotation. . 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. mass of an object and it’s velocity. .. . Formula:. p = . mv. mass . (kg). velocity . (m. ⋅. s. -1. ). momentum (kg. ⋅. m. ⋅. s. -1. ). Unit: kg⋅m⋅s. -1. Momentum is influenced by. What is Momentum? Momentum may be defined by its equation: 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. 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. .
