  • Velocity Explained: Definition, Magnitude & Direction
    Velocity is the rate of change of an object's position over time. It is a vector quantity, meaning it has both magnitude (speed) and direction.

    Here's a breakdown:

    * Magnitude: This refers to how fast the object is moving. It is measured in units of distance per unit time, like meters per second (m/s) or kilometers per hour (km/h).

    * Direction: This refers to the direction in which the object is moving. It can be described using compass directions (north, south, east, west) or angles relative to a reference point.

    For example:

    * A car traveling at 60 km/h to the north has a velocity of 60 km/h north.

    * A ball thrown straight up at 10 m/s has a velocity of 10 m/s upward.

    Key points to remember:

    * Constant velocity means an object is moving at a constant speed in a constant direction.

    * Changing velocity means an object is either changing its speed, its direction, or both.

    * Acceleration is the rate of change of velocity over time.

    Understanding velocity is crucial in physics, engineering, and many other fields.
