Class 11 Physics Work Energy Power Special cases in elastic collision

Special cases in elastic collision :

  • Case 1 – If the two masses are equal m1=m2, then, v1’ = 0 & v2’ = v1
    The first mass comes to rest and pushes off the second mass with its initial speed on collision.

 

  • Case 2 – If m2 >> m1 then , v1» -v1 & v2» 0
    The heavier mass is undisturbed while the lighter mass reverses its ve
