# What maths is in Physics A-Level? watch

1. For those who are taking Physics for A-Level without taking Maths what can you tell me based on what type of math is inside physics and how much.
You know. Generally some information on Physics a level
2. the suvat equations are pretty much 90% of all the maths you would need

Last I did maths was 2 years ago- in a different education system
and I got an A in AS and so far 92% in a recent A2
3. You need to be comfortable linearising equations, using laws of logs, SUVAT, forming vector triangles (and to scale), circular motion, projectile motion.
Most importantly you must be excellent at rearranging equations and be able to derive formulae not given to you in the exam through rigorous practice. There will be no calculus and most of the maths with regard to graphs working out gradients/ areas under line, y-int and x-int. Not much more maths tbf, definitely doable without an entire A level in Maths but by doing Maths, some questions will appear far more approachable
4. I've just started, so i can't be much help on what's covered.. so far i've done some basic algebra. Kinda tricky thing in physics is a lot of the measurements are inconceivably small numbers, so i guess it can be a little tricky to estimate and picture what's really going on. Super interesting though!

If you're taking AQA i would really recommend getting the 'Maths for A Level Physics' companion book by CGP, the book isn't massive and it's fairly inexpensive and it covers all the maths that will be required for the course. Good Luck!
5. - SUVAT equations for mechanics
- Deriving formulae and algebraic manipulation (lots rearranging equations)
- Rearranging equations into a y=mx+c format so you are able to draw a straight line graph (may involve logs in order to do this e.g. for capacitor charging / discharging
- Finding gradients of graphs and areas under graphs (no calculus required though, just drawing tangents onto a curve to work out gradient or counting squares to find area under a curve)
- logarithms and exponentials: being able to solve equations using logs e.g. for electric fields and radioactivity; being able to test whether a graph fits an exponential model)
6. Definitely worth taking A level maths if you want to do the full two year A Level in physics; it would be a real extra burden on you with doing extra maths work in order to help your physics and you are likely to full back behind the majority who will be doing maths. As my post above said, you don’t need to know calculus, but this can be really helpful if you do because then you can see where all these equations that you will use come from, e.g if you differentiate the equation for magnetic flux you get the equation for emf (so you immediately know that the gradient of a flux against time graph gives you emf in case you forget)
