Etymology

Origin of rock¹

First recorded in 1300–50; 1905–10 rock ¹ for def. 10; Middle English rokk(ke), from Old French roche, ro(c)que; compare Provençal, Spanish roca, Italian rocca, Medieval Latin rocca, rocha (becoming late Old English -rocc in stānrocc “stone-rock, obelisk”); cf. roche alum

Origin of rock²

First recorded in 1100–50; Middle English rokken, rocken, rocke(n) “to rock (a cradle),” Old English roccian; cognate with Middle Dutch rocken “to stir, make move,” German rücken “to move, shift,” Old Norse rykkja “to jerk, pull”

Origin of rock³

First recorded in 1690–1700; short for rockfish

Explanation

If you are asked to rock a baby, please do not throw a stone at it. Instead, move the baby gently from side to side. If this doesn't calm the child, play some loud rock music. When rocking a baby you move gently, but when you're told not to “rock the boat” the rocking movement referred to is more violent, enough to tip the boat over. This kind of motion has more in common with what you do when “rocking out” listening to music. A rock is also a lump of mineral, and if we say someone is "like a rock," we mean he's totally dependable.
