How Can I Master Kinematics in Two Dimensions?

AI Thread Summary
Mastering kinematics in two dimensions can be challenging, especially after grasping one-dimensional concepts. It's essential to have a solid understanding of one-dimensional kinematics before tackling two dimensions, as movement in one direction does not influence movement in another. Online resources, including tutorials and YouTube videos, can provide valuable guidance. Engaging with forums for specific questions and sharing work can also enhance understanding. Utilizing these resources can significantly aid in mastering the complexities of 2-D kinematics.

Having diffuclty understanding the concepts, etc. I did alright for one dimension, but now I am pretty lost. I have trouble knowing what to find and how to draw everything out. (Chapter 3, Cutnell & Johnson, 7th Edition). Does anyone have any recommendations on online outlines or even youtube videos to help? Anything is appreciated, thanks

This forum might be a good place to start! :biggrin:

You can search google for help on 2-D kinematics tutorials though, I'm sure there should be some out there. One way to make the jump to 2-D kinematics is be on solid footing for 1-D kinematics. I think another thing that trips people up is thinking that movement in one direction effects movement in the other, which it doesn't. Feel free to post a question on the forum (with work provided and in the appropriate section) if you need help.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
