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

The nerve impulse The information is transmitted by polarity changes in the membranes of cells due to the presence of neurotransmitters that alter the ionic concentration inside the cell. Moreover‚ inside the neuron proteins and ions are negatively charged . This difference in ion concentration also produces a potential difference between the outer membrane and within the cell . The value reached is about -70 millivolts (negative inside with respect to the value of positive charges outside

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

Faber‚ University of Minnesota ABSTRACT - Much of the work on impulse buying has been concerned with defining and measuring the concept. Less effort has been directed toward determining the factors that underlie the tendency to buy impulsively. This study looks at the relationship between impulse buying tendencies and three general personality

RUNNING HEAD: IMPULSE CONTROL DISORDER Impulse-Control Disorder Impulse-Control Disorders Impulse-Control Disorder (ICD) is a repeated impulsive action that results in negative consequences. The DSM-IV distinguish five particular impulse-Control Disorder such as: kleptomania‚ pyromania‚ pathological‚ trichotillomania‚ and intermittent explosive disorder. The DSM-IV-TR named these five disorders “Not Elsewhere Classified” and names them separately
