In physics:
If the direction doesn't matter, the word "speed" is used.
If the direction DOES matter, the word "velocity" is used.

Why do you measure bowler's throwing ball as speed but not velocity?
Speed and Velocity are the same thing, it is a measure of rate of change of position of an object.
What happens to an objects acceleration when an unbalanced force is applied?
There's no such thing as "an unbalanced force".When the group of all forces acting on an object is unbalanced,the object accelerates, in the direction of the sum of all the forces,and at a rate that's proportional to the strength of their sum.If the group of all forces acting on an object is balanced, meaningthat the strength and direction of all of them adds up to zero, thenthe object moves at a constant speed in a straight line, which is thedefinition of zero acceleration.
An object is in motion only if its distance from a reference point is?
An object is in motion only if its distance from a reference point is changing. The average speed of the object is given by the object's rate of change of displacement from the reference point over time.
What happens to the reaction rate when reactants particles collide more often?
In brief, the reaction rate increases. When there are more collisions, the more probability to collide them in the proper direction. The overall reaction will come to the equilibrium in a lesser time.
How does temperature affect reaction rate hot?
The Hotter the temperature, the faster the particle moves. During the reaction, atoms transfer in different molecules (or compounds), therefore the temperature does affect the speed of the reaction.
What term means the rate at which an object moves?
speed
What describes the rate at which an object moves?
The rate at which an object covers distance is called the object's "speed".If the direction of its motion is also stated, then you have the object's"velocity".
The rate at which an object moves is called?
Velocity
What two things must you know to determine speed?
Speed is the rate at which an object moves. To determine the rate at which that object moves, we'll have to look at a given distance that it covered when it moved, and at the time it took to cover that distance. The distance per unit of time is the speed of the object.
What changes as an object moves with a constant acceleration?
During constant acceleration, either the object's speed changes at a constant rate, or the direction of its motion changes at a constant rate, or both.
What is The rate which an object moves in a given direction?
It is the object's velocity.
Is the rate of change of an object?
the object's "speed"
What is the rate of motion of an object in a linear object?
That is the object's 'speed'.
The rate at which 'n' object moves is called?
Speed. Perhaps also velocity, although the rigorous definition of velocity includes direction (a vector).
The motion of an object that moves at a constant rate?
its uniform.
What is The motion of an object that moves at a constant rate?
Uniform.
What is an objects average speed when an object moves over a distance of 500 meters in 25 seconds?
rate x time = distance rate = distance / time rate = 500/25 Rate=20 meters per second
