The small amount of vector work you may have done at GCSE, or just avoided, needs to be upgraded to A-level standard. Skipping out on this is a huge mistake. Every student who does comes to regret it later. You will do small problems that challenge just the right amount, pushing your understaning a little bit at a time until you understand how and more importantly WHY and WHEN to use the techniques you are learning. Then it’s problems time, involving the different kind of vectors you know, force, speed, displacement and acceleration. The examples will be from real-life, like landing a plane with a wind blowing into you.

This builds on the work you did in the vectors section. Namely that the up and down motion is constant acceleration, as the only force is weight, down. This means constant acceleration, i.e. SUVAT equations. SUVAT equations will be fully explained for every situation you will encounter in the exams. Left and right there are no forces, so the GCSE equation distance = speed x time is all you need. The left and right motion are linked through t, time. Each concept will be added in one a time with small questions to embed it. Then onto the past paper questions that can choose from any of the concepts you been taught.

Yep, it’s not Young’s but Young. Lesson 1 over! Young Modulus is so easy when you realise that it’s just the spring/stiffness constant from Hooke’s law you may remember – but for just steel, instead of that particlar steel spring. A thinner longer steel spring will have the same Young Modulus but a different spring/stiffness constant. We will derive energy per unit volume is the area under the stress/strain graph in a few minutes.

At A-level phase plays a bigger role, especially in comparing travelling and stationary waves. It also plays a big part when you come to single slit, double slits and diffraction grating questions. Understanding path difference leads to understanding interference and then to understanding slits/gratings. You will learn WHY refraction occurs only at an angle. And you will be shown how to do photoelectric effect questions with simple numerical examples along with other quantum topics. It’s actually easier than you thought.

Explained by making you think about a mass wobbling on a spring. Once you have that mental image and anaylse it, the equations come to life. Then with a bit of maths, you will finally know if you need to use SHM or circular motion. And if you do, how to. Circular motion is just basic displacement, velocity and acceleration under very slightly more complex situations. The understanding you will get from circular motion will increase your confidence in other areas, not add another area to worry about.

Gravity first, then electrostatic, then magnetic. Use gravity to understand the principles – force vs field strength, then potential vs potenial energy. A great couple of tricks that help massively. Onto electrostatics with one extra principle. Then magnetism which is a genuine step up in difficulty. You will have everything explained so you understand the big difference between the motor effect and magnetic induction. Why Fleming’s left hand rule works. You will start by understanding what creates a magnetic field (a moving charge) and build from there.
