What is the best way to get better in projectile motion? Does anyone have any good resources regarding projectile motion practice. I have a strong feeling it's going to be in this year's hsc
Your feeling probably isn't unjustified because it always is.
But seriously, just do past papers. Even extract the projectile motion questions out of trial papers if need be. And don't be scared to look at the answers if you've genuinely tried and you're stuck.
The point is to train yourself in ways of thought. Know the rote processes (eg. greatest height) and what not, and then think outside the box from there.
