This example shows how to find the initial vertical velocity of an object if its maximum height (apex) is known.
In this problem, experimental data is used to obtain a value for “g”, acceleration due to gravity.
Here is your HW covering the end of unit 1 and the start of unit 2. This exercise is slightly longer (7 questions) so that you won’t have to do any HW over the Christmas holidays. Make sure you hand in your answers no later than Monday 15th December.
Here is your HW on density and pressure. You’ll be happy to hear that it’s a shorter exercise than the last one. Remember to show your working and hand in your HW jotter by next Wednesday (26th) period 5.
Here is your homework for next Wednesday (12th November). I have taken these questions from a SQA source to illustrate the various formats used for examination questions at Higher. You should attempt all 7 questions.
The first 5 questions are a selection of different styles of multiple choice question. I have chosen questions to test aspects of unit 1 that we have already covered. You should show all of your working for these questions, do not answer by simply writing a letter A-E.
The next 2 questions demonstrate the longer exam style. These are representative of the questions you may meet in a NAB or Section B of an exam. Again, show all working.
…but only after you have submitted your jotter!!
Seriously though, I have discovered that it’s quite straightforward to get worked solutions in a video format so that iTunes will take them as a video podcast. All of the HW from just before the holidays is now ready to go in iTunes and I would like you to try subscribing to the podcast to see if we can all get it to work.
What does this mean? Well, you will need to have some software installed on your computer that can monitor podcasts, iTunes is a popular route for this but other software such as Juice (windows, mac, linux) or Ziepod (windows) will also work for you.
If you have iTunes installed, just find the little button on the right of this page that says “iTunes” in it. Click on the button and it should open iTunes on your computer, starting at my podcast page. All you need to do then is hit the subscribe button next to the picture to start downloading the files. You can then transfer these to your iPod, phone, mp4 player in the same way as you would transfer music or films.
For any other service, such as Juice or Ziepod, you need to right-click on the link that says “RSS: Podcast” and copy the link URL. Now open your aggregator program and go to the screen that lets you subscribe to a new podcast and paste in the URL from your clipboard.
If anyone needs some help with this, come and see me and I’ll try to get it working for you.
Note: when you get the files, you’ll notice that they have been shrunk to the size of an iPod screen. This means so you can’t watch them very easily on a PC anymore. Go back and use the video links from Youtube if you want to use a computer to watch them.
