How can you relate newton's third law of motion(action and reaction) as to why a boat moves forward when you paddle the oars?

Umm...
Well, when you paddle you "push" on the water with the oars. The drag of the oars through the water provide a force towards the back of the boat. Because there is nothing in front of you and the only other force acting on the boat is the drag of the boat's hull in the water (which is hopefully less than the force of the rowing) it pushes you forward... your action is pushing with the oars, your reaction is movement forward through the water.

The force you apply to the oars back wards, it applies the same amount of force on you and the boat forward. Why u move forward is because the oars face greater resistance in the water than you and the boat face air resistance. The water does move backward but you and the boat move forward over a greater distance.

During the rowing of a boat, the boatman pushes the water backwards with the oars. The water exerts an 'equal & opposite' push on the boat which makes the boat move forward.

Puh the paddles. The paddles push water. The water pushes back on the paddles. The paddles then push you the opposite direction you push them. Therefore you (and the boat) move forward.

When you push the oars backwards, it resembles action. Then when the boat moves forward, it resembles reaction. Understand ???

You push water and it pushes you.
