Curve Ball Lab - MATH 273
Subject:
Math 273 ? Lab 1 ? F 07 Curve Balls and Vectors Does a baseball pitch really curve or is it some sort of optical illusion? Assume the pitcher's mound is at the point (60, 0, 0) and that home plate is at the origin of our coordinate system. Suppose the pitcher throws the ball toward home plate and gives it a spin of s revolutions per second about a vertical axis through the center of the ball. This spin is described by the spin vector s where s points along the axis of revolution with length s. From aerodynamics we learn that this spin causes a difference in air pressure on the sides of the ball and results in a spin acceleration on the ball given by , where c is some empirical constant and is the velocity vector. The total acceleration of the ball is then ,

Simple Harmonic Motion Answers (2)
Subject:
4.1 Simple harmonic motion 1a. [4 marks] This question is about simple harmonic motion (SHM). The graph shows the variation with time of the acceleration of an object X undergoing simple harmonic motion (SHM). Determine the maximum displacement of X. Give your answer to an appropriate number of significant figures. Markscheme use of ; or or ; } (allow answers in the range of T = 7.8 to 8.0 (s) or = 0.785 to 0.805 (rad s)) ; (allow answers in the range of 4.0 to 4.25 (m)) two significant figures in final answer whatever the value; Award [4] for a bald correct answer. Examiners report Similarly, this was well done. Most appreciated the need to truncate the final answer to a sensible number of significant digits (two in this case). 1b. [2 marks]

Chapter 18 Notes
Subject:
Chapter 18 Electric Forces and Electric Fields 18.1 The Origin of Electricity The electrical nature of matter is inherent in atomic structure. coulombs 18.1 The Origin of Electricity In nature, atoms are normally found with equal numbers of protons and electrons, so they are electrically neutral. By adding or removing electrons from matter it will acquire a net electric charge with magnitude equal to e times the number of electrons added or removed, N. 18.1 The Origin of Electricity Example 1 A Lot of Electrons How many electrons are there in one coulomb of negative charge? 18.2 Charged Objects and the Electric Force It is possible to transfer electric charge from one object to another. The body that loses electrons has an excess of positive charge, while
