## 20 AugWhat do you need to know about Quantum Physics?

The sequence of development of quantum mechanics, summed up for IB students, from me:   (1) Hydrogen atoms emit a discrete spectrum of light.  This is our first evidence that energy levels in the atom are quantized.  What a mystery!  Physicists have never seen something like this before.   (2) Balmer comes up with...

## 12 AugWhat do you need to know about Oscillations and Waves?

a a Thermal physics provided the transition from macroscopic physics to microscopic physics, and electricity is all about electrons, so why are we backtracking now to talk about bouncing springs and wiggling strings?   It's because waves are going to be essential, ultimately, to our understanding of the inner...

## 05 AugWhat do you need to know about Thermal Physics?

a I love physics, but I used to think this one topic, thermal physics, was boring.  I had to teach it twice before I understood it well enough to see how interesting it really is! a What makes thermal physics interesting is that it provides a link between...

## 30 JulWhat do you need to know about Electric Charge and Field?

a There are only four fundamental forces in physics, and in high school physics we will learn about three of them.  These forces are called "fundamental" because we don't have a deeper explanation for why they exist.  The four are Gravitational Force Electric Force Strong nuclear...

## 02 JulWhat do you need to know about Forces & Newton’s Laws of Motion?

a A force is just a push or a pull There are lots of ways to push or pull: Gravity pulls objects down toward the ground.  We call that force the weight of the object.   A string or rope can pull on an object.   Springs can do...

## 01 JulWhat do you need to know about Free-fall, Projectile Motion, Air Resistance, and Terminal Velocity?

a Free-fall:  a special case of uniformly accelerated motion a When you drop a hammer, it falls to the ground.  While it is falling, the only force acting on it is gravity. (There's also a little bit of air resistance, but for a hammer moving at relatively low...

## 28 JunWhat do you need to know about Measurement & Uncertainty.

Yes we know. Fascinating and intriguing may not be the first descriptors that come to mind at the very mention of this topic. In fact, and also very unfortunately, it has been a sufferer of chronic neglect by generations and generations of students (and even teachers) :( Mundane...

## 25 JunWhat do you need to know about Kinematics?

Defining Velocity Velocity is the rate of change of position. If you go in a straight line from A to B, your velocity is just the distance between A and B divided by the time it took to go from A to B. e.g. If the straight-line distance...

## 19 AprSec 4 Physics Term 2 Newsletter – Sec 4 Physics MYE Revision

Salutations Sec 4 Physics students, how's revision coming along? We sincerely trust that most of you are at least halfway done already Or better yet, done with revision :D Well...
