When the mover pushes the box, two equal forces result. Explain why the box moves even though the forces are equal and opposite
The net force causing acceleration is zero, so it continues in constant motion.
when the mover pushes the box, it pushes it at a rate so it will move
When the mover pushes the box, two equal and opposite forces are at play. According to Newton's third law of motion, for every action force, there is an equal and opposite reaction force. In this case, the mover is exerting a force on the box, and the box exerts an equal force back on the mover.
While these forces are equal and opposite, they act on different objects - the mover and the box. As a result, each force has a different effect on the corresponding object. The force exerted by the mover pushes the box, while the force exerted by the box pushes against the mover.
The reason the box moves is that the force applied by the mover is not counteracted by an equal and opposite force acting on the box. Any forces opposing the box's motion, such as friction, have to be less than the force applied by the mover. Thus, there is a net force applied to the box in the direction of the mover's push, causing it to accelerate and move.
In summary, even though the forces are equal and opposite, they act on different objects, creating a net force on the box that enables it to move.
