Physics often scares people even before they take the subject or solve a physics question. It can be very complicated as...
17 Mar Survive in Junior College
Junior College, or more fondly known as JC, is an adventure on its own with the many ups and downs and unexpected challenges. These tips would hopefully be of help in helping you navigate this labyrinth.
Understand the question requirements
The methods you...
1) Classrooms in schools are far too crowded
Singapore’s a pretty small country, with a population that’s far too large. Our overcrowded classrooms are a byproduct of this phenomena. In primary school, it’s not uncommon for a class to have up to 40 students;...
??? ??????? ??? ?????????.
At PMC, we have a huge community of students who are self-motivated and independent. Most voluntarily seek tuition classes from their parents as they want to make their learning efficient under tutor of their choice. We are naturally the No 1...
Physics is an important subject that combines math and science to explain how the world works.
Here are some tips that will help you succeed and send you into that exam ready to win!
Don’t Wait Until Exam Time
To do well on a...
Stars form from enormous clouds of hydrogen atoms, pulled together by the force of gravity. As the cloud collapses, gravitational potential energy is converted to kinetic energy of the atoms (they are all “falling” toward their common center of mass). If a...
Rutherford Experiment (aka Geiger-Marsden)
Rutherford shot alpha particles at a thin film of gold foil
Most of the alpha particles went right through
Some had high angles of deflection
He was shocked when a small number of the...
Thermal Energy Transfer / Greenhouse Effect
IB calls this topic Thermal Energy Transfer, but really it’s about the greenhouse effect and climate change. Calling it Thermal Energy Transfer it sounds more physics-y.
Climate change is of course a controversial subject. Before...
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.
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...
