Question

you are carrying a stack of boxes across the room. when you come to a sudden stop, some of the boxes fall forward off of the top of the stack. which law of motion is it?

Answer 1

The phenomenon of boxes falling when stopping suddenly is an example of Newton's First Law of Motion, which encapsulates the concept of inertia.

Step-by-step explanation:

The law of motion in question when the boxes fall forward off the stack when stopping suddenly is Newton's First Law of Motion. This law is sometimes referred to as the law of inertia, which states that an object in motion will remain in motion with a constant velocity, and an object at rest will remain at rest, unless acted upon by a net external force. In the case of the stack of boxes, the boxes want to continue moving due to their inertia when the person carrying them comes to a sudden stop. However, since there is no longer any forward force being applied to keep the boxes moving when the person stops, they fall forward due to their inertia. The net external force causing the change in motion for the boxes is the person stopping, which acts in the opposite direction of the boxes' motion.

Answer 2

this is the law of inertia.
