Mod 5 physics (2 Viewers)

Ok now since Im done with projectile motion in mod 5 I havent come across this formula:


Is this from the old syllabus or something that pops in mod 5 later on? idk I searched the syllabus/ textbooks and couldnt find this so just making sure

thanks

its a formula u can derive using integration. i think u can also derive it using the suvat eqns asw but im unsure. that there is the formula for the maximum height approached by the proj motion.

its like a handy tool ig but you're better off not memorising it imo. maybe for practise you could derive it so you can see where it comes from

is there a reason why not to memorise it? it doesnt seem that bad

You can't quote formulas not on the data sheet -> must prove them

ohk

Im guessing you have done hsc physics
have you used this formula a lot during ur physics journey? want to see how important it is

yeah this is the reason. you can't use it straight up in the hsc. its only useful for multiple choice bc no working is needed (unlikely tho) and maybe its useful for quickly checking your answer for a longer question ig

Not particularly, projectile motion questions tend to be test only once or twice throughout the entire paper and are usually considered 'lower band' questions

It's used for symmetrical projectiles only I'm pretty sure. Like people have said above, any equations in physics that are not on formula sheet you need to remember to derive or you lose marks. But just remember for multiple choice imo.

oi you done w mod 5?
