This behavior is explained by Newton’s first law of motion, which states that an object at rest will remain at rest unless acted upon by an unbalanced force.
What principle explains why our body will remain at rest unless acted upon by an unbalanced force?

The principle that explains why our body will remain at rest unless acted upon by an unbalanced force is Newton’s First Law of Motion. This law states that an object at rest will stay at rest, and an object in motion will stay in motion with a constant velocity unless acted upon by a net external force. Inertia, the tendency of an object to resist a change in its state of motion, is a fundamental concept related to this law. The presence of an unbalanced force is required to overcome inertia and initiate motion or alter the existing state of motion.
