yawing:
Yawing is motion around the ship's vertical axis.Yawing involves rotation of the ship around its vertical axis. This occurs due to the impossibility of steering a ship on an absolutely straight course. Depending upon sea conditions and rudder deflection, the ship will swing around its projected course. Yawing is not a cause of shipping damage.
pitching:
Pitching is the movement of a ship around its transverse axis.In pitching a ship is lifted at the bow and lowered at the stern and vice versa. Pitching angles vary with the length of vessel. In relatively short vessels they are 5° - 8°C and sometimes more, while in very long vessels they are usually less than 5°.During upward motion, stack pressures rise, while they fall during downward motion.
Rolling:
Rolling is the movement of a ship around its longitudinal axis, the rolling angle in this case being 10°.Rolling involves side-to-side movement of the vessel. The rolling period is defined as the time taken for a full rolling oscillation from the horizontal to the left, back to horizontal then to the right and then back to horizontal. In vessels with a high righting capacity, i.e. stiff ships, rolling periods of 10 seconds and below are entirely usual. Rolling angle is measured relative to the horizontal. Just in moderate seas, even very large vessels roll to an angle of 10°.n bad weather, angles of 30° are not unusual. Even the largest container ships must be expected to roll to such angles. Stabilizers and other anti-heeling systems may help to damp ship movements. However, not all systems are usable or sufficiently effective in bad weather.

Rolling: sideways motion of a ship
Yawing: moving side to side
Pitch: up & down movement as the bow and stern rise and fall with the waves
