If you did 2unit HSC maths, if you liked the Question 9's or 10's involving physical problems then you will like Physics.
it just says 3u is assumed knowledge... what mark did you get in that?
im pretty sure it said 2u mathematics is assumed in my first mechanics lecture notes.
differentiation
integration
graphs
exponentials
trigonometry
etc.
but thats just the tip of the iceberg.
but if you did ext. 1 or ext. 2 it would benefit even more.
Even the Physics topics in 3u such as Simple Harmonic Motion (x" = - ωx) and in 4u, Mechanics aren't even explicitly in HSC Physics because of their highly mathematical nature and are best explained using hsc maths.
They will return in First Year Physics.
I chose Physics 1A cause I thought it be a better transition to Uni by doing easier courses.
Both Physics 1A and Higher Physics 1A students learn the SAME topics in lectures, go to the SAME tutorials and SAME labs with each other.
The only difference is Higher Physics 1A students always gets more questions and likely harder questions in assessments.
