  • Velocity Explained: Definition, Magnitude, and 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: How fast an object is moving. This is typically measured in units like meters per second (m/s) or kilometers per hour (km/h).

    * Direction: The direction the object is moving. This could be north, south, east, west, or any combination of these.

    Key points about velocity:

    * Constant velocity: An object moving at a constant speed in a straight line has constant velocity.

    * Changing velocity: If an object changes speed, direction, or both, its velocity changes.

    * Average velocity: The total displacement of an object divided by the total time taken.

    * Instantaneous velocity: The velocity of an object at a specific moment in time.

    Example:

    A car traveling at 60 mph east has a velocity of 60 mph east. If the car turns north, its velocity changes, even if its speed remains the same.
