Positive work in physics indicates that energy is being transferred to an object, moving it in the direction of the force applied. If the force applied and the object's movement are aligned (less than 90 degrees apart), the work is positive. An example includes pushing an object across a surface, which is a case of positive work done on that object. ;

Positive work in physics means energy is transferred to an object, making it move in the direction of the applied force. This occurs when the force and the movement are aligned (less than 90 degrees). Therefore, the correct answer is C: The environment did work on an object.
