Preface

General

This module is part of a collection of modules designed to make physics concepts accessible to blind students.

If you opened this page in the context of the book, a Table of Contents for the book (or collection) should be available above and to the left of thisparagraph. Otherwise, click here to open the book at the beginning.

This book is intended to supplement but not to replace the textbook in an introductory high school or college physics course.

The purpose of this module is to explain variable velocity and acceleration in a format that is accessible to blind students.

Prerequisites

In addition to an Internet connection and a browser, you will need the following tools (as a minimum) to work through the exercises in these modules:

  • A graph board for plotting graphs and vector diagrams ( (External Link) ).
  • A protractor for measuring angles ( (External Link) ).
  • An audio screen reader that is compatible with your operating system, such as the NonVisual Desktop Access program (NVDA), which is freelyavailable at (External Link) .
  • A refreshable Braille display capable of providing a line by line tactile output of information displayed on the computer monitor ( (External Link) ).
  • A device to create Braille labels. Will be used to label graphs constructed on the graph board.
  • The ability to create tactile graphics as described here .

The minimum prerequisites for understanding the material in these modules include:

  • A good understanding of algebra.
  • An understanding of the use of a graph board for plotting graphs and vector diagrams ( (External Link) ).
  • An understanding of the use of a protractor for measuring angles ( (External Link) ).
  • A basic understanding of the use of sine, cosine, and tangent from trigonometry ( (External Link) ).
  • An introductory understanding of JavaScript programming ( (External Link) and (External Link) ).
  • An understanding of all of the material covered in the earlier modules in this collection.
  • An understanding of the creation and use of tactile graphics as described here .

lack electricity and its more savely than electronic microscope because its naturally by using of light
Abdullahi Reply
advantage of electronic microscope is easily and clearly while disadvantage is dangerous because its electronic. advantage of light microscope is savely and naturally by sun while disadvantage is not easily,means its not sharp and not clear

in what situation (s) would be the use of a scanning electron microscope be ideal and why?
Kenna Reply
A scanning electron microscope (SEM) is ideal for situations requiring high-resolution imaging of surfaces. It is commonly used in materials science, biology, and geology to examine the topography and composition of samples at a nanoscale level. SEM is particularly useful for studying fine details,

what is cell division
Aron Reply
Cell division is the process by which a single cell divides into two or more daughter cells. It is a fundamental process in all living organisms and is essential for growth, development, and reproduction. Cell division can occur through either mitosis or meiosis.
