Hi physics lovers,
Here is a movie showing you how to find the total time of flight of a projectile.
Hi Physics lovers!
Here is a method to find the maximum height reached by a projectile.
My first year class were given a task to adopt a famous scientist at the beginning of the session.
They were told to collect some information, write it out themselves and make a podcast to share with students around the world.
Click on the picture below to hear their speeches.
A big thing about being a scientist is that you need to communicate.

Once there please click the run now box and use your investigation sheet to answer the questions.
Hi Physics lovers! Here is the answer video for Assessment 002Q1.
When you start the movie you can press the small controls to view fullscreen.
Hi physics lovers. Here is the link to download the Higher Physics Assessment 02A.
Hi Physics lovers, here are the answers to the homework problems 1.24 to 1.29
1.24 Displacement = -30.6m so depth = 30.6m
1.25 Displacement = -0.82m so height dropped = 0.82m
1.26 (a) 0m/s
(b) 10m
(c) -14m/s ie 14m/s going down
(d) 2.86s
1.27 (a) From the instant it is released it will be subject to negative acceleration -9.8m/s2 So its velocity will decrease to zero and then increase negatively until it strikes the ground.
(b) Displacement = -32.1m so height = 32.1m
(c) Final velocity = -25.4m/s
1.28 (a) 1.53s
(b) 11.5s
(c) 14.7m
1.29 (a) 6.1s
(b) 183.7m
Mr Mallon
Jamie Lang of Mr Mallon`s Physics class shows how to measure the speed of sound using two microphones attached to an electronic timer.
The distance between the microphones was 1 metre.
Download speed of sound worksheet here.
Mr Mallon`s second year science class used their mobile phones to take pictures of cells.
Using their magnifying capability we examined the cells in detail and discovered each cell has a nucleus.
Andrew Jackson brought in some pond water which was teaming with microscopic life. Check out the amazing picture of a midge larvae captured in class. Awesome picture.
Thanks to Andrew Jackson for providing the pond water.
PS Mobile phones in class can be a powerful tool when used appropriately, well done S2.
