Hi Physics lovers.
Here are the links to the two little movies you watched in class today.
I have included three more for you to watch and study.
Eureka Episode 1
Eureka Episode 2
Eureka Episode 3
Eureka Episode 4
Eureka Episode 5
S3 Physicists helped build a wonderful wave machine out of jelly babies and bbq sticks.
We also have made a movie which will be online shortly.
Well done S3 physicists!
Have a look at this projectile movie.
Hi physics lovers! Here is a projectile movie made in class last year.
It shows that the horizontal motion of the projectile is independent of the vertical motion.
In other words, if a machine ejects a ball with a horizontal velocity while at the same time dropping another ball then both balls will take the same time to hit the ground!
No matter how fast the horizontally moving ball moves away it will still strike the ground at the same time as a ball dropped at the same time and at the same height.
PhET Projectile Experiment.
Use the PhET simulation sheet, there is a link below, to experiment with the cannon.
Download experiment sheet here
Link to PhET projectile site where you can download the virtual experiment or press run to have it on a bigger screen.
Hi physics lovers. Here is the first nasty 7 test of the session.
Remember it is only nasty if you have not studied.
Hi Higher physicists. Find below your second assignment. If you can you cam print it out and hand it in on Tuesday.
Our third year physics class began building a wave machine from jelly babies, barbeque sticks and a roll of duck tape!
We hope to have a video made. In the meantime check out what the video should look like below.
Click the above picture to take you to our virtual experiment to find the link between the wave speed, wavelength and frequency.
Have some fun. If the wave disappears press the reset button.
If you know that the speed of sound is 340m/s then you can work out how far away a thunderstorm is from your position.
The video below taken from Mr Mackenzie`s wonderful fizzics website. shows a thunderstorm in progress.
Time how long the thunder comes after the flash and use this time to calculate how far the thunderstorm is away.
