because that's how it moves and to keep straight
To move a boat using oars is to row a boat. The action of the oars in the water propels the boat. In ancient times, rowing vessels were used in naval warfare and trade.
The homophones for "oars" and "noisy fight" are "oars" and "oars" ("-oars" and "oars").
It's Row
ballsIF YOU FELL FOR IT
by using its sails and if theres no wind they use oars
A paddle boat uses oars called paddles. Instead of a engine and steering wheel to move about on the water.
its a row
When you row a boat on a pond, you are usually facing the back of the boat. Also, the oars are usually attached in the middle of the oar to the side of the boat. So if you pull the handle of the oar towards the front of the boat (towards you when rowing), the paddle of the oar is moving towards the back of the boat (the oar acts like a lever-arm). To move a boat forward, you actually have to move water backward! It's pushing water back that really moves the boat forward. So, when you pull the oar towards you, the paddle moves towards the back of the boat, and that pushes water towards the back of the boat, pushing the boat the opposite direction, which is forward! Just make sure to turn around once in a while because you're not looking where you are going!
row
That is called rowing. A boat can also be propelled with one oar off the stern and that is called sculling.
They can't simply go back and forth because otherwise they wouldn't move anything. If a boat moves itself because it pushes the water, then it has to change the position of the oars (take it out of the water and rotate it) in order to repeat the movement. If cilia also don't change their position, they would simply move the mucus back and forth and it wouldn't get anywhere. Cilia also rotate in another direction to reach their starting point.
