Question: 1 / 400

What is defined as the change in position of an object?

Movement

Displacement

The correct answer is displacement, which specifically refers to the change in position of an object from its initial point to its final point. Displacement is a vector quantity, meaning it has both a magnitude and a direction, indicating not just how far the object has moved but also in which direction it has moved.

In contrast, while movement describes the act of changing position, it doesn't quantify or specify the change, nor does it provide information about direction. Distance simply measures how much ground an object has covered during its motion, regardless of direction, making it a scalar quantity. Acceleration is defined as the rate of change of velocity of an object, which relates to how quickly an object changes its speed or direction, but it does not specifically describe the object’s change in position. Thus, displacement is the most accurate term for the change in an object's position.
