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.

Ever wondered which is faster between light and sound?

Well our new standard grade physics class along with our technician Mr McKenna set out to race sound and light.
We used a special machine that activated a flash lamp when it detected sound. So the light flashed at the same time as the sound was created.

Can you think of anything in nature where sound and light are created at the same time?
Who will win the race. Check out the video!

During my visit to CERN I had the privilege to speak to particle physicist Rolf Landau. Rolf gave our sixteen strong Scottish physics teachers (plus about fifty English physics teachers) three lectures on the history of particle physics.
Rolf also hosted a couple of question and answer sessions about various aspects of what is happening at CERN.

It was Rolf`s introduction about the curiosity that is needed to become a great physicist that caught my imagination.
I took the opportunity to ask him to record that advice to the many Scottish young people who are about to take up Physics.
You`ll find the recording below.

Rolf works on antimatter and was a consultant to Dan Brown`s Angels & Demons movie.

Hi Physics luvvers! Here is your last Nasty Nine of the season. Remember it is only nasty if you have not studied;-)

Started Standard Grade Physics with my new S3.
We thought about what we would explore on our two year journey as though we were embarking on a similar journey into space.

As a class we wrote down what areas of knowledge and expertise would be needed to make the space journey successful.

Well what we wrote down was remarkably like the topics we will be studying over the next few years.

Well done S3 and the best of luck for your Standard Grade journey into physics.
