    Study Notes

    Motion in a Straight Line: Distance and Displacement

    • Displacement is not always zero, even if the distance is zero
    • Distance is not always equal to zero if the displacement is zero
    • Distance and displacement are different physical quantities
    • For motion in one direction without changing direction, Distance = |Displacement|.
    • When a particle changes direction, Distance > |Displacement|
    • Distance traveled by an object is always greater than or equal to the magnitude of its displacement
    • Displacement is independent of the choice of frame of reference
    • The distance covered by an object is never less than its displacement
    • Displacement can be zero while distance is non-zero.Distance can be greater or less than displacement.
    • Distance is a scalar quantity and displacement is a vector quantity.
    • Distance and displacement are measured in the same units (e.g., meters).
    • Displacement can be negative if its direction is opposite to the positive direction.
    • If an object moves along a straight line without changing directions, its distance will always be greater than or equal to the magnitude of its displacement.
    • If an object moves in a straight line but changes directions, its distance will always be greater than its displacement.
    • The distance traveled by an object is always a positive quantity.

    Important Concepts

    • Distance: Total length of the path covered by an object. Scalar quantity. Always positive.
    • Displacement: The shortest distance between the initial and final position. Vector quantity. Can be positive, negative, or zero.
    • Rest and motion are relative terms; it depends on the frame of reference
