collision in 1 dimention

collision in 1 dimention

1. elastic

   • where P & K.E remain conserve
   • to prove
     • law of conservation of momentum
       • +
         • K.E remain conserve
           • relative velocity after collision = relative velocity before collision
             • formula for v1'
             • formula for v2'
   • casses
     • m1=m2 , v2=0
       • m1=m2
         • m1=0. v2=0
           • m2=0, v2=0

2. inelastic

   • where P & K.E does'nt conserve
