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

Case 7.1 Page 138 1) Based on the principles of path-goal theory‚ describe why Art and Bob appear to be less effective than Carol. Path-Goal Leadership: Define Goals‚ Clarifies Path‚ Removes Obstacles‚ Provides Support. Carol is the only one that removes the obstacles. Carol routinely has meetings‚ which she labels troubleshooting sessions‚ for the purpose of identifying problems workers are experiencing. Any time there is a glitch on the production line‚ Carol wants to know about it

1. Discuss why many information technology professionals may overlook project cost management and how this might affect completing projects within budget. One of the most difficult tasks is cost management within an information technology project. An important factor to consider when analyzing the success of cost management practices on a particular project is estimating the various costs that go into an IT project. Many IT projects have very vague or undefined requirements initially so is

Company Case: Bentley Motors: Differentiation and Positioning in International Market The mission of Bentley Motors‚ the definitive British luxury car company‚ to produce best cars in their class‚ has remained unchanged since it was expressed eloquently by its founder Walter Owen Bentley in London in 1919. Located in Crewe‚ England‚ since 1946 and owned since 1998 by Volkswagen AG‚ Bentley Motors is an international company developing and crafting one of the world’s most desirable luxury cars

Business Ethics Fundamental The public view on business ethics has never been high. Many citizens see business ethics as essentially a contradiction in terms‚ an oxymoron‚ and think that there is only a fine line between a business executive and a crook. Public opinion may be reported at 2 levels. At a broad level is the general perception of business ethics by the public and at a narrower level are specific perceptions as to what is going on inside the organization. There is no doubt that the media

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

carrier impulses from the CNS to the periphery‚ the peripheral nerves in turn have the funsion to carry messages from one part of the organism to another‚ so we can understand the action of these drugs. They act in the prevention‚ generation and propagation of the nervous impulse. Acting on the blocking of the depolarization initiation‚ allowing Na + to enter the nerve cell from rest to the trigger threshold (- 50a - 60 mV) would consequently impede the initiation and propagation of the impulse. Therefore

Laboratory V: Conservation of Momentum Problem #1: Perfectly Inelastic Collisions John Greavu April 17‚ 2013 Physics 1301W‚ Professor: Evan Frodermann‚ TA: Mark Pepin Abstract A cart was given an initial velocity toward another stationary cart down a track. The initial velocity of the first cart as well as the masses of both carts was varied throughout multiple trials. Velcro placed on the ends of the carts caused the cars to stick together after colliding. Videos of the collision and the seconds

Lab: Momentum Conservation Abstract This experiment aims to test the law of conservation of momentum by using cart and track system. Procedure 1. Put two carts onto the track. 2. Hit the button on the cart so that they start to move at opposite directions. 3. Find the position where the carts hit the end at the same time. 4. Find the distance that each cart traveled. 5. Repeat step 1-4 with 500g and 1000g weights on one of the carts. Data and Calculation m1m2=x2x1

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
