Does a Fish Have Any Force on a Bobber When It Pulls It Down into the Water?
When a fish pulls a bobber down into the water, it is exerting an upward force on the bobber. This force is equal to the weight of the water displaced by the bobber, which is determined by the volume of the bobber. The larger the bobber, the more water it displaces, and the greater the upward force exerted by the fish.
In addition to the upward force, the fish is also exerting a forward force on the bobber. This force is equal to the drag force of the water on the bobber, which is determined by the speed of the bobber. The faster the bobber moves, the greater the drag force exerted by the fish.
The net force acting on the bobber is the sum of the upward force and the forward force. If the net force is positive, the bobber will move upward. If the net force is negative, the bobber will move downward.
In most cases, the upward force exerted by the fish is greater than the forward force, so the bobber will move upward. However, if the fish is strong enough or the bobber is small enough, the forward force may be greater than the upward force, and the bobber will move downward.
