Formula for Projectile Motion?

Click For Summary

Discussion Overview

The discussion revolves around the formulas related to projectile motion, with participants expressing varying levels of need for specific equations and understanding of the underlying concepts. The scope includes both theoretical understanding and practical application of motion equations.

Discussion Character

  • Homework-related
  • Debate/contested

Main Points Raised

  • One participant requests a clear formula for projectile motion, indicating difficulty in finding understandable resources.
  • Another participant emphasizes the importance of understanding the principles behind motion equations rather than relying solely on formulas.
  • A suggestion is made to refer to an external website that purportedly covers projectile motion comprehensively.
  • A participant lists several equations related to projectile motion, expressing frustration over not being able to access their teacher's notes due to vision issues.
  • Another participant asserts that only three fundamental equations are necessary for understanding motion, although they do not specify which equations they refer to.
  • One participant reiterates the need for multiple equations, arguing against the notion of a single formula that applies universally to all scenarios.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the necessity of a single formula versus multiple equations for projectile motion. There are competing views on the importance of understanding the underlying concepts versus simply obtaining formulas.

Contextual Notes

Some participants express limitations in their understanding due to external factors, such as vision impairments affecting their ability to take notes. There is also a suggestion that the discussion may be more appropriate for a homework or coursework forum.

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.
