Learning Outcome

At the end of this lesson, you will be able to:

• create an application that uses complex math and "large" variable types

Silent Watching

• watch this video
• then this video

Review

• the importance of a good design BEFORE you start coding!

Lesson

• read "Problem Solving", Chapter 2, Computer Based Problem Solving
  • read up to and including "Sequence"

Activity

• read the following problem:
  • Albert Einstein's famous equation E = mc² gives the amount of energy (in Joules) released when an object of a certain mass (in kg) is converted to energy
  • If the speed of light (c) is 2.998x10⁸ m/s write a program that will allow the user to enter the mass of an object and then sees how much energy could be released from that object.
• once your first 3 steps are done, do the next 3 in Java
• post the solution and then the final program on your website
  1. top-down design
  2. flow-chart
  3. pseudo-code
  4. at least three (3) test cases calculated out using some other method then your program (ensure you show how you calculated each one of them out!)
  5. actual code
  6. three screen shots of the program working (with actual values from your test cases above)
  7. link and screenshot of Github repo

Daily Assignment

• once your first 3 steps are approved, code the next 3
  • post the same six (6) items to your notebook

Extra

• answer the following question, with a program
  • "A thousand tons of TNT would release about 4 TJ of energy. Hiroshima released about 63 terajoules (a 15 kiloton bomb). A typical nuke today would carry about 4,000 TJ.", add a second calculation to your above program to show how many "Kiloton bombs" equivalent the number of joules of energy being released.
