It means that an object with a negative average velocity is moving in the opposite direction (of course according to the chosen positive direction of the predefined frame).

What does acceleration mean as a science term?
It's the change in velocity, the rate of change (derivative) which is instantaneous velocity. Acceleration can be positive or negative, meaning increased or decreased velocity respectively.
What is the difference bet increasing acceleration and increasing deceleration?
firstly, we should know what is meaning of accelerate i.e(to increase)that means acceleration is something which increases some physical quantity.In mechanics,acceleration means rate of change of velocity per unit time .a=v-u/twhere v=final velocity, u=initial velocity ,t=time& a=accelerationnow ,if the change in velocity is positive then i.e final velocity is greater than initial velocity.Suppose to be positive acceleration or simply acceleration.But when change in velocity is negative then acceleration is negative suppose to bedeceleration.Important thing is that acceleration is vector .so ,positive or negative accelerationindicates direction of acceleration.hence , force ,by Newton's second law.acceleration tends to increase the velocity of a moving body in the direction of motion while deceleration tends to decrease the velocity of the moving body applies in opposite direction of motion upto zero velocity after which it accelerate means increase velocity of the body but in opposite direction of initial direction of motion.
What is the meaning of the rate of change of velocity?
The rate of change of velocity, either increasing or decreasing, is its acceleration or deceleration.
In velocity do you put the direction?
Yes, always. Velocity is a vector, meaning it has both a magnitude and a direction. You must account for the direction. Speed is the magnitude of velocity and has no direction.
Is it true that Velocity is the speed of the wave?
In common language, the terms "velocity" and "speed" are used interchangeably. In physics, "velocity" is a vector, and "speed" is not - meaning that when the word "velocity" is used, it specifies not just how fast something moves, but also in what direction.
What is the meaning and formula for deceleration?
Deceleration is the rate of decrease of velocity with respect to time. It is the negative of acceleration. The formula for deceleration is the same as that of acceleration, only that the acceleration is represented as negative. The formula is: - (deceleration) = (final velocity) - (initial velocity) time Therefore, (deceleration) = (initial velocity) - (final velocity) time
What does acceleration mean as a science term?
It's the change in velocity, the rate of change (derivative) which is instantaneous velocity. Acceleration can be positive or negative, meaning increased or decreased velocity respectively.
Can the speed of body be negative?
The problem here is the conflating of the term "speed" with "velocity". Velocity is a vector - it has both intensity and direction. Velocity can be negative. Speed really only has magnitude, so it is normally only positive; since there is no direction associated you can't define a meaning for negative speed (unless you decide to define it as synonymous with velocity) When a body is thrown in upward direction and upward motion is defined as positive velocity, its velocity decreases with time and at highest point speed and velocity become zero. When the body falls downward its speed i increases until hit the ground but since it is moving in the opposite of the direction that was defined as "positive", its velocity is negative.
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.
How do you calculate turbulence intensity?
Assuming that you have high frequency velocity measurements it's relatively simple. It is simply the ratio of u' to U - meaning the average fluctuating component of the velocity divided by the mean velocity. I = u'/U :)
What is the product of velocity and speed?
Except for the fact that velocity has a direction, velocity and speed have the same units; so you would have a speed squared (plus a direction). As far as I know, this has no physical significance - meaning that you won't normally carry out this multiplication.

Can a child have o negative if mother is A negative and the father is A positive?
Yes. Because o and negative are both recessive genes. Meaning that the parents can be carriers of these genes without showing physical characteristics.
Why point mobility analysis for automotive parts?
The physical meaning of point mobility is that it tells you how much velocity you can create at that point for a given force, at each frequency. Velocity is used for several reasons, not least of which is that sound pressure generated by a radiating panel is a function of velocity
Meaning for velocity?
Speed.
What is the full meaning of velocity?
quickness of motion : speed the velocity of sound
What is the average velocity of a car that moved 60 km in 3 hours?
The average speed during that time is 20 km per hour. We can't say anything aboutthe velocity because you've told us nothing about the direction it traveled."Velocity" is NOT just a fancy word for 'speed'. It has a different meaning.
