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!

What makes thermal physics interesting is that it provides...

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

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...

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...
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) 🙁

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...
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 😀
Well… if you happen to be one of those who has yet to start, you’re in big trouble...
