These two are synonyms. Both speed and velocity are the time derivative of the diplacement. Confusion may come from the fact that these words are sometimes used to describe a scalar quantity and sometimes a vector qty. Proper usage of these would be in the vectorial form, however, it is often used under the scalar form, when direction or orientation is trivial.

How do you know an objects speed and velocity?
if the objects distance travelled and time is given then speed=distance/time eg- distance travelled 50 mtrs time taken 5 seconds speed 50/5 =10m/s velocity=u(initial velocity 0 for free falling objects) + at(acceleration x time)
It can be important to know the velocity of an object not just its speed because?
We distinguish between speed and velocity because if you add the speedsof objects, their directions are important. For example, the velocity of an airplane with ...
The rate at which something moves?
That is the speed or velocity.That is the speed or velocity.That is the speed or velocity.That is the speed or velocity.
How do you know which has the highest velocity?
its speed
When you know both speed and direction an object in motion you know the?
velocity
What is the difference of an objects speed and an objects volocity?
when you know both speed and direction of an objects motion you know the velocity of an object.
When you know the both speed and direction of an objects motion you know the?
Velocity
When you know both the speed and direction of an objects of an objects motion you know the?
I'm pretty sure its the acceleration. If its not that, its the Velocity.

What do you need know to find an objects velocity?
The distance it travels in a caertain amount of time as well as the direction

How do you find speed if you know the velocity?
Velocity is speed and direction
What do you need to know other then speed to determine an objects velocity?
The direction in which it's moving. This is a very important concept, and a great question.
You do not know an objects velocity until you know what?
To know an object's velocity, you need to know its speed and direction. You can measure speed by calculating how long an object takes to arrive at a new position. So by knowing an object's starting position, ending position, and the time it took to get there, you can calculate its average velocity. In a more advanced calculation, you could choose starting and ending positions that are extremely close to one another and calculate "instantaneous velocity." Velocity is known as a "vector value". A vector not only has a length, but a direction. In this case, "length" is the same as "speed", and direction is its change in position.
When do you know an objects velocity?
When you have calculated or measured it.
