Intro:
The main goal of this experiment is to measure the change in momentum of a cart and compare it to the impulse it receives. For this experiment, a force sensor, motion detector, elastic cord, a dynamics cart and track were used to collect the data. The cart was placed on the track and pushed away from the force sensor until the elastic cord is completely stretched and the motion sensor measured the change in momentum. The goal of this experiment was recorded and calculated using Logger Pro and the equations that were learned in class. The equations were used to test the impulse-momentum theorem.

The short story “A & P” by John Updike is a corky and humorous read. The casual, self-venting, adolescent depiction of an absurd event that unfolded in a small town grocery store is a peculiar and yet entertaining read for all audiences. The theme of this story has to do with adolescent stressors, choices and consequences, and standing up for what one believes is right. The way the author uses the point of view of the young adolescent sales clerk to describe the characters and setting in the story is simply genius. The author’s use of similes, metaphors, and imagery describes the setting and characters in a way that reflects the narrator’s stage in life. In doing this, the story flows perfectly with the three themes presented above.
In the story, the author describes the scene from the point of view of a 19 year old sales clerk working in a small town grocery store. First he describes the narrator’s object of interest and other characters in a similar fashion with the use of imagery and similes. “She was the queen. She didn’t look around, not this queen, she just walked straight on slowly, on these long white prima-donna legs.” And also, “With the straps pushed off, there was nothing between the top of the suit and the top of her head except just her, this clean bare plane of the top of her chest down from the...

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) = d(mv)/dt = dp/dt Therefore, F = dp/dt i.e. the force can be viewed as the rate of the change of momentum This is a much stronger statement than our previous version F = ma Why?
The version F = dp/dt allows for the possibility that not only the velocity, but also the mass can change! Example: rocket filled with fuel is loosing its mass as it burns the fuel.
IMPULSE
F= dp/dt is a differential equation

It can be converted ∆p x = p fx − pix = into an integral form.

Experiment

Projectile Motion
You have probably watched a ball roll off a table and strike the floor. What determines where it will land? In this experiment, you will roll a ball down a ramp and determine the ball’s initial velocity with a pair of photogates. You will use this information and your knowledge of vectors to predict where the ball will land. You will also learn how to determine percent difference between an expected value and measured value.
Figure 1
OBJECTIVES
•
Measure the initial velocity of a ball using two photogates and computer software for timing. • Apply concepts from two-dimensional kinematics to predict the impact point of a ball in projectile motion. • Take into account trial-to-trial variations in the velocity measurement when calculating the impact point.
MATERIALS
Power Macintosh or Windows PC LabPro or Universal Lab Interface Logger Pro two Vernier photogates ball (1- to 5-cm diameter) masking tape ramp carbon paper plain paper meter stick
PROCEDURE
1. Set up an inclined tunnel made of paper on a table so that a ball can roll down it, across a short section of table, and off the table edge as shown in Figure 1. Note: You do not need to make the ramp very high. A smaller gradient works better.

INTRODUCTION
PREAMBLE
Impulse buying is an important phenomenon for researchers in consumer behavior and retailing. A multitude of empirical evidence has been collected in an effort to measure the prevalence of purchases made on impulse. Unfortunately, existing definitions come short of fully capturing the phenomenon, and in turn yield measurements that do not accurately reflect the pervasiveness of impulse buying. The definition offered in this paper will help measure the pervasiveness of impulse buying more faithfully. The proposed definition is constructed on elements from existing definitions, and introduces and defines a new dimension: "on-the-spot."
Impulse buying is a phenomenon that started to trigger consumer researchers' interest forty years ago, Clover, 1950; DuPont Studies, 1945, 1949, 1959, 1965; and West, 1951. In response to this interest, considerable efforts have been invested toward defining impulse buying, and have resulted in a proliferation of definitions....

...pleasure (Silvera, Lavack & Kropp, 2008). Infrequent impulsive buying could be considered non-problematic, similar to alcohol consumption (Silvera et al, 2008). However, because of the hedonistic nature of IBT, chronic levels have the potential to become problematic and destructive (Silvera et al, 2008). In light of this research efforts to understand its causation are greatly increasing.
An empirical study conducted by Verplanken and Herabadi (2001) proposed that a propensity for IBT could be an intrinsic part of personality. The Impulse Buying Tendency Scale (IBTS) was developed as a means to test this theory. It stipulated IBT is driven by two core elements which are broken down into an affective component and a cognitive component. The cognitive component is defined as a lack of planning or deliberation associated with purchase decisions and the affective component is the emotion that is commonly felt prior to, during or after impulse buying, particularly feelings of excitement, pleasure or regret. Verplanken and Herabadi’s (2001) results concluded that IBT correlated with a number of personality based individual difference measures associated with the Big Five personality traits (Verplanken & Herabadi, 2001) in particular that the cognitive component of IBT had a moderately strong negative association with individual need for structure and need to evaluate (Conscientiousness). While the affective component showed a moderately...
