    Study Notes

    1. Speed is how fast something moves, while velocity is speed with a direction.
    2. Speed is measured as distance moved over time.
    3. Speed can be calculated using the formula: speed = distance/time.
    4. Speed is commonly measured in meters per second (m/s) or kilometers per hour (km/h).
    5. Instantaneous speed is the speed at an instant in time.
    6. Constant speed is when the speed does not change.
    7. Velocity is a vector quantity with magnitude and direction.
    8. Velocity uses displacement instead of distance.
    9. Velocity is calculated using the formula: velocity = displacement/time.
    10. Velocity and speed can be different if the direction changes.
