    Graphing

    • Two types of graphs: position vs. time, velocity vs. time.
    • Position vs. time: Straight line = constant velocity (direction). Slope = velocity.
    • Velocity vs. time: Straight line = constant velocity. Downward slope = negative acceleration (slowing down). Area = displacement.

    Mole Equation

    • Calculate mass from number of molecules.
    • Identify ionic compound formulas (like lithium oxide) using "drop and swap".
    • Moles (n) = number of molecules / Avogadro's number.
    • Mass (m) = moles (n) × molar mass (M).

    Mole Equation Manipulation

    • n = m / M
    • m = n × M

    • Adequate sleep.
    • Breakfast, hydration.
    • Avoid cramming (stop studying 2 hours before).
    • Start with confident questions.
    • Skip difficult questions, return later if time permits.
    • Anxiety is normal and can be a motivator.
