key term - $d = |d_1| + |d_2| + ... + |d_n|$

Citation:

Definition

The absolute value of the sum of the magnitudes of individual displacements. This term is used to calculate the total distance traveled by an object undergoing relative motion, where $d_1, d_2, ..., d_n$ represent the individual displacements in a series of motion segments.

5 Must Know Facts For Your Next Test

  1. The term $d = |d_1| + |d_2| + ... + |d_n|$ is used to calculate the total distance traveled by an object undergoing relative motion, where $d_1, d_2, ..., d_n$ represent the individual displacements in a series of motion segments.
  2. The absolute value of each displacement, $|d_1|, |d_2|, ..., |d_n|$, is used to ensure that the distances are added regardless of their direction, as distance is a scalar quantity.
  3. Total distance is always greater than or equal to the magnitude of the net displacement, as the path traveled may involve changes in direction.
  4. This term is useful for analyzing the motion of objects that do not move in a straight line, such as those experiencing changes in direction or reversals in motion.
  5. Understanding this term is crucial for accurately calculating the total distance traveled by an object and distinguishing it from the net displacement, which may be a different value.

Review Questions

  • Explain the difference between distance and displacement in the context of relative motion.
    • Distance is the total length of the path traveled by an object, represented by a scalar quantity with only magnitude. Displacement, on the other hand, is the change in position of an object, represented by a vector quantity with both magnitude and direction. While displacement may change direction and have a net value of zero, the total distance traveled is always greater than or equal to the magnitude of the net displacement, as the object may have changed direction or reversed its motion during the course of its relative movement.
  • Describe how the term $d = |d_1| + |d_2| + ... + |d_n|$ is used to calculate the total distance traveled by an object undergoing relative motion.
    • The term $d = |d_1| + |d_2| + ... + |d_n|$ represents the sum of the absolute values of the individual displacements $d_1, d_2, ..., d_n$ experienced by an object during a series of motion segments. By taking the absolute value of each displacement, the term ensures that the distances are added regardless of their direction, as distance is a scalar quantity. This allows for the calculation of the total distance traveled by the object, which may involve changes in direction or reversals in motion, and is always greater than or equal to the magnitude of the net displacement.
  • Analyze how the understanding of the term $d = |d_1| + |d_2| + ... + |d_n|$ is crucial for accurately describing the motion of an object in the context of relative motion, distance, and displacement.
    • The term $d = |d_1| + |d_2| + ... + |d_n|$ is crucial for accurately describing the motion of an object in the context of relative motion, distance, and displacement because it allows for the calculation of the total distance traveled, which is a fundamental quantity in the analysis of an object's motion. By taking the absolute value of each individual displacement, this term accounts for changes in direction and reversals in motion, which are common in relative motion scenarios. Understanding this term and its relationship to distance and displacement is essential for properly analyzing the motion of objects that do not move in a straight line, as well as for distinguishing between the total distance traveled and the net displacement, which may have different values.
