Every-morning Jake comes out and brings his boat with him to go in. Hes taking his boat with him to go ride in it. But this object is in motion when Jake puts it in the water, because the outside force is acting upon it when the force of the water of the boat is floating of the surroundings of the water that is either against it or pushing it.
But when Jake gets into his boat the matter of the object that he is going into, is that when he gets into it the motion of the amount of force that is acting onto the object and the mass of the object.
While he was in the boat, there is an action that there is an equal and opposite reaction of to what his feet are pushing down on the ground of the boat with the same force that the ground of the boat is pushing back up on his feet.
