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.
