What is the difference between speed and velocity?

bobpursley,
velocity has direction and magnitude, speed has only magnitude.

Dan,
velocity is speed with direction
For example....
An airplane is flying East at 300 miles per hour
Its speed is 300 miles per hour
Its velocity is 300 miles per hour East

calculate the volume of a solid that has a length of 3.1 cm width of 1.9mcm and a height of 2.8 cm

stuart,
Velocity is displacement divided by time, its a vector having both magnitude and direction
Speed is distance divided by time and
is scalar having a magnitude only.
ie. a man runs a race stopping at the finish line, hence 0 displacement and no velocity. He would have speed because he traveled a set distance divided by his time.

Tyler put a cube of blue closed cell foam in a syringe and clamped the the end closed, what happened to the particles outside of the cube?
