    Study Notes

    Scalar and Vector Quantities Overview

    • Scalar Quantity: Describes quantities that have only magnitude, with no specific direction.
    • Vector Quantity: Describes quantities that possess both magnitude and a specific direction.

    Examples of Scalar Quantities

    • Distance: Measurement of space between two points.
    • Speed: Rate of distance traveled over time without direction.
    • Time: Measurement of duration without direction.
    • Power: Rate of doing work or transferring energy.
    • Energy: Capacity to perform work or generate heat.

    Changes in Scalar Quantities

    • Scalar quantities alter only when their magnitude is modified, not based on direction.

    Examples of Vector Quantities

    • Displacement: Change in position of an object, involves direction.
    • Velocity: Speed of an object in a specified direction.
    • Acceleration: Rate of change of velocity, includes direction aspects.
    • Force: Interaction that causes an object to change its motion, defined by magnitude and direction.
    • Weight: Gravitational force on an object, varies by location due to gravity direction.
    • Momentum: Product of mass and velocity, direction matters in its calculation.

    Changes in Vector Quantities

    • Vector quantities change based on:
      • Change in magnitude.
      • Change in direction.
      • Changes in both magnitude and direction.

    Speed vs. Velocity

    • Speed: A scalar quantity indicating how fast an object is moving, irrespective of direction.
    • Velocity: A vector quantity, representing speed in a specific direction; critical distinction from speed.

    Vector Quantity Differences

    • The difference between two vectors is calculated by subtracting the initial vector from the final vector.

    Scalar Quantity Differences

    • The difference between two scalars is found by subtracting the smaller value from the larger value.
