Question

Imagine a system (collection of objects) where the total overall momentum is conserved, but the

momenta of individual objects is not conserved. Can that exist? Explain why or why not, and give
an example to support your argument.

Answer 1

Answer: If the net force of a system is not equal to zero, then the momentum will not be zero

Explanation: If the net force of a system is not equal to zero, then the momentum will not be zero. Friction usually happens when the path of the motion is rough enough; otherwise, there will be no proper hold of the body on the surface. If the energy is not conserved in a collision, then the momentum will also not be conserved.
