What is defined as a moving object in physics?

A moving object in physics is best defined as a projectile. Projectiles are objects that are thrown into the air with an initial velocity and are subject to the forces of gravity and air resistance. They follow a curved path known as a trajectory due to the influence of these forces. In this context, projectiles can include items like a ball thrown, a cannonball shot, or an arrow released from a bow, all of which exhibit motion through space until they hit the ground or reach a target.

Given this definition, the other concepts are distinct from the notion of a moving object. An energy wave refers to a transfer of energy through a medium, like sound or light waves, which doesn't involve a physical object in the same sense. A static body, conversely, implies that the object is at rest and not in motion. Lastly, an external force represents an influence that can cause an object to change its state of motion, but it itself is not defined as a moving object. Therefore, in the context of the question, a projectile is the clear and precise definition of a moving object in physics.
