SUMMARY

The discussion focuses on the challenges faced by a student in memorizing and applying kinematic equations in Physics I with Calculus. The student successfully derives some equations but struggles with 1D and 2D motion problems, leading to point deductions for not including equations in their work. Recommendations include utilizing resources like Khan Academy, Physics Classroom, and HyperPhysics for thorough explanations and memorization techniques. The student expresses gratitude for the provided links and finds them helpful in understanding the derivation of key equations.

PREREQUISITES
  • Understanding of kinematic equations in physics
  • Familiarity with 1D and 2D motion concepts
  • Basic knowledge of calculus principles
  • Experience with online educational resources like Khan Academy and HyperPhysics
NEXT STEPS
  • Explore advanced kinematic equations and their applications
  • Study the derivation of the equation x=x0+v0t+(1/2)at^2
  • Practice solving 1D and 2D motion problems using kinematic equations
  • Investigate additional resources for physics problem-solving strategies
USEFUL FOR

Students enrolled in Physics courses, particularly those struggling with kinematic equations and motion concepts, as well as educators seeking effective teaching resources.

I'm not sure if this should go here, so if it needs to be moved, please feel free to do so.

I really need some help, and I hope the following post makes sense.

I am currently taking Physics I with Calculus and am having some problems. I absolutely cannot remember the kinematic equations, but am able to derive some of them. Also I get so confused when applying the equations, but I can get the answers for the problems by thinking through them. I was asking one of my classmates for help with this today and she could not understand how on Earth I'm solving these things without the equations. This is really problematic because of course I need to learn how to solve things using the equations, and although I am getting the answers correct, I have gotten points deducted because of the equations not being present in my work. I'm doing fine with vectors, circular motion and the other things we have learned, but I have trouble with 1 and 2D motion.

We are going over some quantum mechanics in my chemistry class and I have internalized almost all of the equations and constants, so I really don't know why 1 and 2D motion is not registering! To me the problems seem like things I have been solving without the equations for some time now.

Are there any tips you can give for memorizing these equations or any sources that give thorough explanations about 1 and 2d motion? I have tried some of the pdf files we have in the learning tools section, KhanAcademy, physicsclassroom, and a few other university sites.

Thank you!

Thanks so much Doc Al :) I am looking at the links you gave and I will let you know if this fixes the glitch in my brain :smile:
Edit:
Yes this is helpful already. I always wondered how this equation was derived

displacement & time:
x=x0+v0t+(1/2)at^2
The site you gave explains it.
Thank you so much!
