Velocity is a vector, so you simply use vector properties, noting that speed is a magnitude of velocity. For example:
If velocity is (8x, -4y),
then the speed is:
sqrt(8^2+4^2) = sqrt(68) (by Pythagoras)
and the direction is:
tan(A) = -4/8
A = arctan (-1/2) = -26.56 degrees (or 333.43 degrees)

Is speed equal to velocity?
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
Why is velocity and speed same unit?
Velocity is speed, plus an indication of direction. To indicate a velocity, you can indicate a speed (this will logically use units of speed), and a direction.
How do you find speed if you know the velocity?
Velocity is speed and direction
What does the velocity include that the speed does not?
Direction. Velocity is a vector, speed is a scalar.
What is the Velocity of speed?
Velocity is the vector form of speed. It is the speed of an object in a specified direction.
What is speed in a given direction is called?
Speed in a given direction is velocity.
What is speed in a given direction?
Speed in a given direction is called velocity.
What is the speed in any given direction?
Speed in any given direction can be calculated using vector addition and represents the total magnitude of velocity without regard to direction. It is the sum of the speeds in each individual direction.
What is the speed of an object plus its direction?
The speed of an object plus its direction is called velocity. Velocity is a vector quantity that combines the object's speed (magnitude of the velocity) and its direction of motion.
When you change speed and direction you are changing what?
When you change speed and direction, you are changing your velocity. Velocity is a vector quantity that includes both speed and direction. So when you modify either speed, direction, or both, you are altering your velocity.
How is velocity different from average speeed?
Velocity is speed and its direction. Average velocity is average speed and its direction.
Does velocity depends on both speed and direction?
Yes, velocity is a vector quantity that depends on both speed (magnitude of velocity) and direction. Changing either the speed or direction of an object will result in a change in its velocity.
The direction and speed of an object is described by its?
The direction and speed of an object is described by its velocity, which is a vector quantity that includes both magnitude and direction.
What is the speed and direction of an object called?
The speed and direction of an object is called its velocity. Velocity is a vector quantity that includes both the magnitude (speed) and the direction of motion.
Is speed velocity in a given direction?
Yes, speed is the magnitude of velocity. Velocity includes both the speed and the direction of motion. So speed is a scalar quantity, while velocity is a vector quantity.
The speed of an object and the direction of its motion?
the object's 'velocity'
Is speed equal to velocity?
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
