Why is an oar a second class lever Giving reasons?
The answer is that it is NOT. It is a first class lever. "Class 1: the fulcrum is located between the applied force and the load. Example: the crowbar" - Wikipedia In regular use, the fulcrum of the oar is attached to the top side or edge of the water craft, which is between the force being applied by the rower and the "load", being the resistance of the water itself. This makes the oar a classic example of a first class lever.
When you row a boat on the pond why does the boat go forward when you are pulling the oars towards you?
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!
What is an oar's fulcrum?
Imagine a giant rock, what is the most efficient way of lifting this rock (obviously without machinery)? The simple answer would be to use a lever, put the end of the bar under the rock and apply weight on the other end. The same concept applies to rowing. The blades are placed in the water (under the rock), and you pull on the blade handles (apply weight to the end of the lever/bar). The water is moved (the rock lifted) but more importantly the boat is pulled out of the water upon which it glides along. In this way the oar or a rowing boat is a lever. (as you can see rowing is a very technical sport since the rower has to understand all this and manipulate the given elements- the boat , the stroke and how they move the boat through the water-so as to be as efficient as possible and as fast as possible.

Why is an oar a class 2 lever?
An oar is a class 3 lever. This is because the oar, like all class 3 levers, is not used to reduce the force needed to move the load, but is used to increase the amount of travel of the load.

Is an oar a first class lever?
Yes, but its Mechanical advantage is usually less than 1
What force used to row the boat?
It's a mechanical force exerted through a lever called an oar, acting through a fulcrum called a rowlock attached to the side of the boat. The rower pulls the oar towards the bow of the boat, which causes the other end of the oar to push back on the water. The water tends to stay where it is and there is a net forward force on the rowlock, which pushes the boat forwards.
