Question

Why don't action and reaction forces on a person swimming in water cancel each other out

Answer 1

Action and reaction forces are equal and opposite forces, but they don't cancel each other out because the forces are on different parts of the person swimming in the water.

Answer 2

They Act on Different Objects

Step-by-step explanation:

Newton's Third law of motion states that action and reaction are equal and opposite. The action and reaction forces in of Newton's Third Law -works on different objects.

In Real life examples, or situations like, A textbook lying on a table ever, A cup pressing down on the table, or a table pressing up on an iron, these forces in this cases, are balanced by extra or additional forces, and at times, they are not.

Most importantly action and reaction forces from Newton's Third Law of motion act on different objects, But forces working on the same object or entity may cancel out this is from( Newton's Second Law), So long as the sum of their is considered to be zero.
