speed
In physics:
If the direction doesn't matter, the word "speed" is used.
If the direction DOES matter, the word "velocity" is used.
The rate at which something moves is known as speed or velocity.
the answer is rate
average speed
Velocity
Speed and Velocity are the same thing, it is a measure of rate of change of position of an object.
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 changing. The average speed of the object is given by the object's rate of change of displacement from the reference point over time.
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.
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.
speed
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".
Velocity
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.
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.
It is the object's velocity.
the object's "speed"
That is the object's 'speed'.
Speed. Perhaps also velocity, although the rigorous definition of velocity includes direction (a vector).
its uniform.
Uniform.
rate x time = distance rate = distance / time rate = 500/25 Rate=20 meters per second
