How does the law of conservation of momentum apply in a perfectly elastic collision?
Answer 1
Sean Rivera Jr.
In a perfectly elastic collision, both momentum and kinetic energy are conserved. The total momentum of the system before the collision equals the total momentum after the collision. Mathematically, if two objects with masses m1 and m2 have initial velocities u1 and u2, and final velocities v1 and v2, the conservation of momentum is expressed as: m1*u1 + m2*u2 = m1*v1 + m2*v2.
