    Study Notes

    Scalar vs. Vector Quantities

    • Scalar quantities have only magnitude, such as temperature or mass, but no direction.
    • Vector quantities have both magnitude and direction, such as force or velocity.

    Motion Types

    • Translational motion refers to motion where the trajectory is always a straight line; this includes types of uniform motion.
    • In uniform rectilinear motion (URM), an object travels in a straight line with constant speed.

    Examples of Quantities

    • Scalar quantity examples include distance, speed, and energy.
    • Vector quantity examples include displacement, velocity, and acceleration.

    MRU (Motion in a Straight Line)

    • MRU stands for "Uniform Rectilinear Motion," where an object moves with constant speed along a straight path.

    Addition of Scalar Quantities

    • Scalar quantities are added arithmetically by simple addition, as they do not involve direction.
