Explain me Prateek Sir.
Dear Student ,
|The law of conservation of momentum states that:|
"when some bodies constituting an isolated system act upon
one another, the total momentum of the system remains constant."
"the total momentum of an isolated system of interacting bodies remains constant."
"Total momentum of an isolated system before collision is always equal to total momentum after collision."
|Consider an isolated system of two bodies 'A' and 'B' as shown. The masses of bodies are ma and mb and|
|Consider two bodies of mass m1 and m2 moving initially with velocities u1 and u2.|
|Total momentum before collision = m1u1 + m2u2|
|Let after collision their velocities become v1 and v2.|
|Total momentum after collision = m1v1 + m2v2|
|According to the law of conservation of momentum|
m1u1 + m2u2 = m1v1 + m2v2
