Formula for Projectile Motion?

AI Thread Summary
A clear understanding of projectile motion requires familiarity with multiple equations rather than a single formula. Key formulas include Vx = x/t, x = vt, y = Vgt + 1/2gt^2, v = voy + gt, and vy^2 = voy + 2gy. Additional essential equations are v = u + at, s = ut + 0.5at^2, and v^2 = u^2 + 2as. Relying solely on memorization without comprehension can hinder problem-solving abilities. Mastery of these concepts is crucial for success in physics.

Can someone post a decent formula? I can't seem to find something that I can understand.

There isn't a magic formula, if you don't understand an equation for motion, you need to learn why.


What do you want to know about projectile motion?
 
I just need the formulas..i only have notes on formulas like Vx = x/t, x = vt, y = Vgt + 1/2gt^2, v = voy + gt, vy^2 = voy + 2gy. I wasn't able to copy my teachers notes on the other formulas due to my nearsightedness and her handwriting was so small I can barely see it.
 
You just need 3 equations.
v = u + at
s = ut + 0.5at^2
v^2 = u^2 + 2as

There is no such thing as ONE formula that fits all scenarios. If you think there is, then there's a good chance you'll not do well with such problems, because you are hoping to only do a plug-and-chug without any understanding.

If this is related to a schoolwork, it should have been done in the HW/Coursework forum.

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
