What is defined as a body's change in position concerning a fixed point?

• A. State of motion
• B. Trajectory
• C. Displacement
• D. Speed

Answer: (A)

The concept that describes a body's change in position concerning a fixed point is known as displacement. Displacement refers to the vector quantity that indicates the shortest distance from the initial position to the final position of an object, along with the direction of that change. Displacement takes into account both the distance and direction, making it a more comprehensive measure when analyzing motion in physics. It reflects not just how far an object has moved but also in which direction it has moved in relation to a specified point. The term 'state of motion' generally refers to the overall status of an object in terms of its movement, which does not specifically define change in position in relation to a fixed point. Similarly, 'trajectory' describes the path that a moving body follows through space but does not quantify the change in position itself. Finally, 'speed' specifies how fast an object is moving but lacks direction, thus it does not adequately capture the concept of change in position concerning a fixed point as displacement does.
