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. 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.. 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. . 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.. 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?. 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.. Movement around a fixed point or axis. Spin; somersault . Occurs when a force is applied outside the centre of mass. 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. Section. 2: Velocity and Momentum. Section 3: Acceleration. Section 1: Describing Motion. Motion occurs when an object changes its position. You need a reference point to know whether an object has changed its . 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. by Zack Ridgway and Jeffrey Wan . Kinetic energy. Kinetic energy- energy of an object that it possesses due to its motion. . Common examples. A baseball thrown by a pitcher, although having a small mass, can have a large amount of kinetic energy due to its fast velocity.. 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 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. .
