If according to Newton’s Third Law of Motion, every force has an equal and opposite force, then does it mean that every force in the universe cancels? Explain
According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. This means that whenever one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.
However, it's important to note that these paired forces act on different objects and not on the same object. They do not cancel each other out. The forces in a pair always act on different objects, and they are never on the same object simultaneously.
For example, consider the interaction between two billiard balls. When you hit one ball with the cue stick, the cue ball exerts a force on the target ball, pushing it away. At the same time, the target ball exerts an equal and opposite force on the cue ball, causing it to move backward. The forces are equal in magnitude but act on different objects, resulting in both balls experiencing motion.
This principle can be extended to any force interactions in the universe. Forces can cause objects to accelerate, change direction, or deform, but they never cancel each other out. Newton's Third Law simply states that forces come in pairs; they are always equal in magnitude but act on different objects, leading to a change in the motion of those objects.
