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) =

Cranial Nerves The brain and spinal cord (CNS) are connected to parts of the body by nerves and cell bodies called the peripheral nervous system. The PNS contains all of the nervous tissue outside the brain and spinal cord. Afferent (sensory) nerve fibers-conduct nerve impulses toward the CNS Efferent (motor) nerve fibers-conduct nerve pulses away Sensory Somatic System – Carries nerve impulses from the senses to the CNS and also carries the impulses to the skeletal muscles and glands

Neurophysiology Study Guide 1. Define "equilibrium potential". Why is the resting potential closer to the potassium equilibrium potential (EK+) than the sodium potential (ENa+)? The equilibrium potential is the point at which the force exerted on an ion by electrostatic and concentration gradient forces are balanced‚ and there is no net movement of that ion. The resting potential is closer to EK+ than ENa+ because the cell membrane is more permeable to

Cranial Nerves The human body is a unique and fascinating entity. There is not much notice taken of the features the human body is capable of. The brain is necessary to perform day-to-day actions‚ such as the ability to speak‚ and see amongst us. This brain is made up of simple mater (Pia mater‚ Arachnoid mater‚ Dura mater) and the cranial surface to protect the brain. We live our daily lives without acknowledging the importance of this organ‚ the brain‚ unless you’re a medical student of

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

Social Networking on the internet and social media has changed the way that the world does business and operates. You can no longer stick to the traditional ways of reaching customers such as newspaper ads or flyers sent through the mail. Although these forms are still used and I’m sure they are quite successful‚ nothing beats word of mouth and nothing beats word of mouth shared through

The vagus nerve is the tenth of the twelve brain nerves. The vagus nerve contributes to the feelings associated with infections such as appetite‚ fatigue and induction of disease behavior. It extends from the brainstem to the abdomen‚ with branches in the neck‚ thorax and abdomen 68. The vagus nerve is part of the autonomic nervous system‚ has efferent fibers‚ ascending signals from the brain to the peripheral organs‚ as well as afferent sensory fibers‚ and transmits information from the peripheral
