Final answer:
The principle describing that a soccer ball will remain where it landed until kicked is Newton's First Law of Motion or law of inertia, which states that an object at rest will stay at rest unless acted upon by a net external force.
Step-by-step explanation:
The question you're asking about, "a soccer ball will stay where it landed until a person kicks it," refers to Newton's First Law of Motion, also known as the law of inertia. 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. In the case of the soccer ball, it will remain where it landed because its inertia keeps it stationary until a force, such as a kick from a person, changes its state.
A soccer player, gravity, air, and friction commonly exert forces on a soccer ball, affecting its motion both when it's kicked and after it lands. When a ball is in motion, air resistance and friction will eventually slow it down and bring it to a stop, demonstrating Newton's First Law.
