and dirty secrets of a twisted mind‚ a serial killer stalking his prey in the subway. And Duncan can’t stop reading. What would you do with a book like that? How far would you go to catch a madman? This is the teaser to an amazing book I read “Acceleration” By: Graham McNamee. Duncan the main leading character of the story discovers a journal belonging to what he thinks is a serial killer and he uses his knowledge of profiling as well as the clues from the journal to try to decipher who the serial

April 29‚ 2014 Abstract The objective project was to use our knowledge of physic properties to create a working car that was powered by a mouse trap. I found that the lighter the car was and the more traction the car had‚ the further it travelled. Introduction The purpose of this project was to create a car that is powered by a mouse trap. We were to use our knowledge of physics laws to make the best car we can. I knew from Newton’s Law‚ F=ma‚ that if my car had a lower

necessary to produce a temperature change of 1°C per gram of substance. The specific heats of different substances vary‚ and therefore this quantity may be useful in identifying an unknown. The measurement of heat changes is called calorimetry. In this lab activity‚ calorimetry will be used to determine the specific heat of an unknown metal. This will be done by using a styrofoam cup calorimeter containing water. A calorimeter is insulated so as to minimize any loss of energy to the surroundings. Therefore

Physics Lab Report#3 “Determining the period of a pendulum” Name: Fei Huo Date performed: October 1st‚ 2014 Period 5 Teacher: Mr. Glasel Purpose: The Purpose of this Lab was so that my classmates and I can examine what kind of factors affect the period of a pendulum. Introduction: In a simple form‚ the pendulum is a weight hung from a long string that Galileo discovered that it can be used to track the passage of time very accurately around 400 years ago. In this

In this experiment we tested the idea that no matter what the size‚ shape‚ color‚ etc. of the object if it would still experience the same constant acceleration throughout its fall (short distance). The constant downward acceleration it experiences

Law of Acceleration (1907) by Henry Adams (1838-1918) Images are not arguments‚ rarely even lead to proof‚ but the mind craves them‚ and‚ of late more than ever‚ the keenest experimenters find twenty images better than one‚ especially if contradictory; since the human mind has already learned to deal in contradictions. The image needed here is that of a new center‚ or preponderating mass‚ artificially introduced on earth in the midst of a system of attractive forces that previously

Lab II‚ Problem 3: Projectile Motion and Velocity Oct. 06‚ 2013 Physics 1301W‚ Professor: Hanany‚ TA: Vladimir Abstract A ball is tossed obliquely. The vectors of position and velocity are measured. The acceleration is calculated. Introduction A toy company is now making an instructional videotape on how to predict the position. Therefore‚ in order to make the prediction accurate‚ how the horizontal and vertical components of a ball’s position as it flies through the air should

force and motion I problem 1 The figure below is an overhead view of a 12 kg tire that is to be pulled by three ropes. One force (Fl‚ with magnitude 50 N) is indicated. Orient the other two forces F2 and F3 so that the magnitude of the resulting acceleration of the tire is least‚ and find that magnitude if (a) F2 = 30N‚ F3= 20 N; (b) F2= 30 N‚ F3 = 10 N; and (c) F2 = F3 = 30 N. problem 2 A weight-conscious penguin with a mass of 15.0 kg rests on a bathroom scale (see figure below).

Objective: To study the conservation of energy and momentum using projectile motion. Theory: The ballistic pendulum demonstrates both the constant horizontal velocity in projectile motion and the conservation of momentum. Because there is no acceleration in the horizontal direction‚ the horizontal component (v_x) of the projectile’s velocity remains unchanged from its initial value throughout the motion. In a closed isolated system‚ if no net external force acts on a system of particles‚ the total
