2 Dimensions 41 Newtons second law and momentum Newtons second law states that the acceleration produced by a force on an object is directly proportional to the net force and inversely proportional to the mass of the object . 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. 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. 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. . Houze. , Jr., 1996: . . Momentum . budget of a squall line with . trailing . https://. www.youtube.com/watch?v=hTZI-kpppuw. 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.. Pg. 222- 227. Momentum & Impulse. The driver of this race car walked away from the car without a scratch. Luck had little to do with this fortunate outcome though – a practical application of Newton’s laws of motion by the engineers who designed the car and its safety equipment protected the driver from injury. Have you ever wondered…. How a tae kwon do expert can break a stack of cement blocks?. Why falling on a cement floor hurts more than falling on the grass?. Why a follow through is important in golf, baseball or boxing?. State the principle of conservation of momentum.. Demonstrate the principle of conservation of momentum.. Solve problems about conservation of momentum.. Discuss conservation of momentum in e.g. collisions, spacecraft, aircraft.. Chapter 9. Copyright © 2014 John Wiley & Sons, Inc.

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. 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? 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. 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.
