Question

When two objects interact, the change in momentum of the first object is ______ the change in momentum of the second object.

Answer 1

Answer:

A. Equal to and Opposite

Explanation:

           when there is no External force acting on the system of bodies then Net momentum of the system is Conserved .

        Given that there are 2 bodies

         Let  P₁ as first object's momentum

                  P₂ as second object's momentum.

                  Total Momentum =P₁ + P₂

           As there is no external force acying on the system

                 Change in the Total momentum is zero

so,

                  0 = Δ P₁ + ΔP₂

                   ΔP₂ = -ΔP₁

                   negative sign indicates opposite direction.

                       Both are of equal magnitude.
