  • Understanding Velocity: Speed and Direction Explained
    To describe the velocity of an object, you need two things:

    1. Speed: This tells you how fast the object is moving. It is the magnitude of the velocity.

    2. Direction: This tells you which way the object is moving.

    For example:

    * A car traveling at 60 mph east has a velocity of 60 mph east.

    * A ball thrown upwards at 10 m/s has a velocity of 10 m/s upwards.

    Key points:

    * Velocity is a vector quantity, meaning it has both magnitude and direction.

    * Speed is a scalar quantity, meaning it only has magnitude.

    * Velocity can be positive or negative, depending on the direction of motion.

    Therefore, simply saying "the object is moving at 10 m/s" is not enough to describe its velocity. You need to specify the direction as well.
