Chapter 9 IMPULSE AND MOMENTUM COLLISION PROBLEMS A tennis ball and racket collision: a microscopic view COLLISION: FORCE VS TIME GRAPH A large force exerted during a small interval of time is called an impulsive force. LINEAR MOMENTUM The product of the particle’s mass and velocity is called the linear momentum p = mv As a vector quantity‚ the momentum can be represented in terms of its components: px= mvx py= mvy ALTERNATIVE FORM OF NEWTON’S SECOND LAW F = ma = m(dv/dt) =

MOMENTUM QUESTIONS 1. Which has greater momentum: a train at rest or a moving skateboard? Since the train is not moving‚ it has zero momentum. The skateboard‚ as long as it has some speed‚ will have more momentum‚ since p = m*v. 2. What are the ways to increase impulse? Impulse depends on the magnitude of the applied external force and the time that the force acts on the system. By increasing either of those‚ impulse on a system will be increased‚ and the system’s momentum will change accordingly

Angular momentum and its properties were devised over time by many of the great minds in physics. Newton and Kepler were probably the two biggest factors in the evolution of angular momentum. Angular momentum is the force which a moving body‚ following a curved path‚ has because of its mass and motion. Angular momentum is possessed by rotating objects. Understanding torque is the first step to understanding angular momentum.<br><br>Torque is the angular "version" of force. The units for torque are

Rebecca Nov. 2013 Kyle‚ Mat‚ Alex Lab M7 Conservation of Momentum Abstract: This experiment involved the use of gliders on an air track which nearly isolates the colliding system from external forces to create low friction totally elastic and inelastic collisions. Seven different collisions were made‚ four elastic and three inelastic. The collisions consisted of only two gliders with varying masses and speeds. Each glider cart was equipped with a flag‚ and its passage through a photogate

Physics G Unit 6 – Momentum Internet Lab – Momentum and Collisions Name: Date: Period: Website: http://phet.colorado.edu/ Play with the Sims Physics Motion Collision Lab Introduction: When objects move‚ they have momentum. Momentum‚ p‚ is the product of an object’s mass (kg) and its velocity (m/s). The unit for momentum‚ p‚ is kg·m/s. During a collision objects transfer momentum to each other‚ resulting in different motions than before the collision. In this activity you will study

Encoding Information with Light’s Orbital Angular Momentum Light is the future of communication‚ traveling at 3‚000‚000 meters per second‚ the cosmic speed limit of the universe. Its tremendous speed makes it optimal for data transmission. The conventional method to encode information in light is through amplitude modulation‚ i.e. light pulses‚ time division multiplexing‚ i.e. delaying the time light beams enter a channel‚ and wavelength multiplexing‚ i.e. multiple beams of light in one channel

Conservation and Environmental Protection in the UAE Introduction – The world is on global village not just through connectivity but also in the fact that we all share this earth and must work at saving and preserving its natural resources not just for us but also for our children. That’s why conservation and environmental protection has always been an essential part of the efforts to make the UAE the country it needs to be. To understand how to protect the land and environment‚ we must understand
