Dear OCEAN GODRE,


 


1) learn the corodinate systems thoroughly


 


there are 3 coordinate systems\


a)   cartesian coordintae systems

using these coordinates u can solve momentums and energy in XYZ coordinates


example :  momentum along x-aixs     m1*v1+m2*v2=m1u1+m2u2 like this


 


b)polar coordinates


 


spherical coordinates system is confusing but see the directions of  r, θ, Φ  so that u can dived momentums along those axes.

Cylindrical coordinates

x=rcosθ


y=rsinθ


z=z


 


these are the 3 important coordinate systems u have to remember.


 


using these coordinate systems we can ddived energy conservatios impulse momentum and rotational into 3 axes. after that apply conservation of momentum in x direction and y direction and z direction


 


after that u have to have knowledge on how many types of energies are there. kinetic(if m has some speed) , potential(if m has some height) , rotational( if m is rotating)


impulse =mv/t


 


K_{rotation} = \frac{1}{2} I \omega^2

where


ω is the angular speed
 I \ is the moment of inertia
