PPT-Momentum Momentum is mass times velocity. Momentum is represented by p.

p mv Momentum is a vector quantity The direction of momentum always matches the direction of velocity Momentum A small object traveling at a great speed has a high momentum A large object traveling at a slow speed can have a small momentum. Lots of fun!. Win . valuable prizes!. 1.The reason padded dashboards are used in cars is that they . look nice and feel good. . decrease the impulse in a collision. . increase the force of impact in a collision. . 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.. 2 . Dimensions. 4.1 Newton's second law and momentum. Newton's 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 . Introduction to Momentum. What is Momentum?. The quantity of motion of a moving body. Depends on mass and velocity. Measured by multiplying mass to the velocity. Vector. Measured in kg*m/s or N*s. How is momentum measured?. (d)define . linear momentum as the product of mass and velocity. (e) define force as rate of change of momentum. (f) recall and solve problems using the relationship F = ma, appreciating. that acceleration and force are always in the same direction. 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.. You’re Quite Impulsive. A Review of What We Know About Motion. Chapters 2 & 3 introduced us to vectors such as displacement, velocity, and . acceleraton. No mass was included. Chapter 4 introduced forces and mass into the mix. 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. 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. 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. 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. 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 Specification Forces and motion Forces, movement, shape and momentum know and use the relationship: momentum = mass × velocity p = m × v use the ideas of momentum to explain safety features
