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) =

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

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

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

Finite Element Analysis Introduction Finite element analysis (FEA) has become commonplace in recent years‚ and is now the basis of a multibillion dollar per year industry. Numerical solutions to even very complicated stress problems can now be obtained routinely using FEA‚ and the method is so important that even introductory treatments of Mechanics of Materials – such as these modules – should outline its principal features. In spite of the great power of FEA‚ the disadvantages of computer

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
