Our technical people have made us a great new resource: a tube which is drilled with tiny holes. When we push gas through the tube and light it, we get a long line of little flames. Now, when sound waves are pushed into the tube through a loudspeaker, the resulting pressure waves inside the tube produce visible sound waves in the flames. This is a Rubens Tube and it's brilliant.

Relativistic Mass and Energy

[LESS INFO] 2 VIEWS | ADDED 22:20:00 06/29/09
This tutorial addresses what you need to know for Advanced Higher Physics as far as those equations for relativistic mass and energy are concerned. Two key equations are described: with a very short explanation of what makes up the total relativistic energy of an object with mass, when travelling at speeds of a significant fraction of the speed of light.

Here is the derivation of the three same equations of motion you derived in Higher Physics, this time for Advanced Higher, using integral calculus.

Helicopter problem (Higher)

[LESS INFO] 9 VIEWS | ADDED 20:34:47 06/18/09
This is a worked solution to a problem involving the firing of a missile from a moving helicopter. It analyses motion vectors into orthogonal component vectors, then uses these results to answer the question "where will the missile land?". The problem as posed was: A helicopter travelling at an angle of 10 degrees up from the horizontal at a speed of 70 metres per second fires a missile at 150 metres per second. Calculate the horizontal and vertical components of the velocity of the helicopter and the missile. If the helicopter launches the missile at a height of 200 metres, how far away does the missile land?

Higher Golf Ball problem: part 1

[LESS INFO] 6 VIEWS | ADDED 10:09:42 06/15/09
Part 1 of a worked solution to the following problem: A golf ball is driven at an angle of 30 degrees to the horizontal at a speed of 12 metres per second. Calculate the horizontal and vertical components of the velocity and thereby the maximum height of the ball, the time of flight and the distance travelled when it lands.
