Systems of particles Conservation of linear momentum Explosions and collisions Cats playing with Newtons cradle Lecture 15 Linear momentum Linear Momentum Newtons 2 nd law    . 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. 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. . 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?. Physics 7. th. edition. Classroom Response System Questions. Chapter 7 Impulse and Momentum. Interactive Lecture Questions. . 7.1.1. An astronaut drops a golf ball that is initially at rest from a cliff on the surface of the moon. The ball falls freely under the influence of gravity. Which one of the following statements is true concerning the ball as it falls? Neglect any frictional effects.. F = Δp/t. Δp = Ft. Impulse is defined as the force times the time over which the force acts. Impulse = Ft = Δp. In order to change the momentum of an object, two quantities are important (Force and time). 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. s. Compare the inertia of a semi truck and a roller skate… . Will the truck always have more inertia than the roller skate? . Will it always have more momentum than the roller skate?. Warm-Up. Estimate the amount of work the engine performed on a 1200-kg car as it accelerated at 1.2 m/s. 9. Kinetics. 2.
