1. In the context of describing an object's position, the term "origin" refers to a fixed reference point from which measurements are made. It serves as the starting point for a coordinate system, allowing for the precise determination of the object's location.

  3. The velocity of an object can be changed by altering its speed, changing its direction of motion, or both. Any modification in speed or direction results in a change in the object's overall velocity.

  4. For an object moving along a straight line at a variable speed, average velocity is calculated by dividing the total displacement by the total time taken. This provides the overall rate of change of position, regardless of variations in the object's speed during the motion.

  5. The physical quantity represented solely by its numerical value is speed. Speed indicates how fast an object is moving without considering its direction, distinguishing it from velocity, which includes both magnitude and direction.
