We measured people’s reaction time in class today using this BBC site. Click on the picture to try again at home.
It is important to consider reactions when we measure short times. In Physics, we often try to avoid reaction times affecting our results by using data loggers and light gates to take accurate time measurements.
Read about using light gates to measure average speed and instantaneous speed on pages 6 & 8 of your Transport booklets.
If you can’t get to school due to the weather, here is some work for you to do at home. We will start the Transport topic when we have finished our Investigations. Please use these notes to begin looking at the Transport unit.
Read the notes on average and instantaneous speed and try the questions. If you have a printer at home, please also try to print out the pages with squared sections to practice drawing speed-time graphs.

Here is your HW exercise on the speed & acceleration work we have just covered in class. Please hand your HW jotter in no later than Friday 4th December.
I’ve had an email from Yenka to say that they are now offering many of their products for home use – free of charge! I think Yenka is the new name for Crocodile Clips, the company who made Crocodile Physics and Crocodile Technology. Their software allows you to create your own experiments to learn about
They also have some chemistry products you might find helpful.
The software is free but you can only use it at home. Why not download it and see if you find it useful.
We’ve completed the unit of Transport now. I have uploaded the summary notes we went through on forces, work, power and energy. I’ve also made up 2 sets of notes to show you how to work your way through different types of problems based on potential and kinetic energy. All of the documents are pdf files.
When we started the transport unit a couple of weeks ago, we investigated the reaction times of different people in the class by getting them to time how long it took for Andrew’s plasticine to fall from the ceiling to the floor.
I found a great game on the BBC website that will allow you to measure (and perhaps improve) your own reaction time . Why don’t you try it for yourself and post your best times in a comment.
