Velocity = Delta-x / Delta-t, where x is position, t is time, and "Delta" is the "Change in" operator.
Velocity is a vector, so I probably should have written x as x, or x-arrow, or some other notation to indicate it was a vector quantity, but putting an arrow hat on something is a little difficult to do here, and just making it bold is kind of subtle and could be missed.
Speed is the magnitude of the velocity vector.

∙ 9y agoTo determine the speed of an object, one has to know the distance the object has traveled (in meters) and the time it has taken for the object to travel that distance (in seconds). To calculate speed, take the distance traveled and divide it by the time. To determine velocity, simply take the speed and determine which direction the object was travelling.

What is the term used to describe the rate of an objects movement?
velocity
What is an objects velocity?
An object's velocity is it's speed plus direction. example: 55mph south Hope this helps:)
How the velocity of an escalator that is going up different from the velocity of one that is going down at the same speed?
Speed is a scalar, velocity is a vector. Two objects moving at the same speed but in opposite directions will have opposite velocities. If the velocity of the elevator going up is v, the velocity of the elevator going down will be -v.
When speed changes does its velocity change?
When the object is acted upon by an outside force.
The speed of an object and the direction of its motion?
the object's '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 is the difference an objects speed and an objects velocity?
Speed only tells how fast something is going, while velocity tells speed and direction.
What is a objects speed and direction?
Its called VELOCITY.
What is the difference between a objects speed and an objects velocity?
Velocity also includes direction.
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)
What do you call it when an objects velocity changes?
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
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 measure an objects speed and direction?
Velocity
What describes an objects speed and its direction?
Velocity.
Is velocity an objects speed and direction of motion?
Velocity is an objects speed in a given direction e.g. a runner having run round a circular track of 400m in circumference has 0 velocity.
