What is force
what are unlike parallel forces with example?
What does held nucleons together in a nucleus? Nuclear force. It is the nuclear force which fasten the nucleons together and is responsible for the stability of nucleus.
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
