Projectile motion on the course?

[Andiio]

Do we have to know about projectile motion, specifically the cartesian eqn concept?

i.e. y(x) = xtan(theta) - (gx^2/2V^2cos^2(theta))

Had a look at the study design and it doesn't really specify much on projectile motion with cartesian eqns like the one above.

Thanks!

I would also like to know. My syllabus at school tells us to do every exercise in the textbook EXCEPT the exercise on projectile motion. Hmm...

There's an entire exercise in the heinemann book (which is what we unfortunately use...), devoted to projectile motion, So i assume that we have to know it? :\

you can do projectile motion without even doing the exercises because it is essentially motion with more than one component, so like, i guess it wouldnt hurt to do it, and also, it technically could come up on an exam

Don't treat it as another formula to memorise. Instead, see if you can derive their formula, THAT is the real purpose of its inclusion.

i agree there, too many people become obsessed with formulas, and generally, its much better to think about what's going on and just use kinematics to solve the questions, because when you have air resistance and stuff, formulas dont work anymore
