  • DISTANCE (d)
    • Distance:  The magnitude of the actual distance covered by a moving object from the starting point to the finishing point.

    • DISPLACEMENT (Δx)
    Displacement (Δx): The magnitude and direction of the straight-line distance from the starting point to the end point of a motion.

    Velocity is the rate of displacement.
    Or The rate of change in position.

    • Remember: "rate" means "per unit time".
    • Velocity is a vector quantity and is measured in m.s-1. 
    • Average velocity is calculated using the following equation:
            𝐴𝑣𝑒𝑟𝑎𝑔𝑒 𝑣𝑒𝑙𝑜𝑐𝑖𝑡𝑦 = 𝑑𝑖𝑠𝑝𝑙𝑎𝑐𝑒𝑚𝑒𝑛𝑡/𝑡𝑖𝑚𝑒
