Something is decelerating . I.e it's still going forward, but at a reduced and falling speed.

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.
Does an object that is moving in a linear path with an acceleration in the direction opposite to the motion have a decreasing velocity?
No. Acceleration is Delta-Velocity / Delta-Time. If Acceleration is negative then that means that either Delta Velocity is negative or Delta Time is negative---which is not practical. For Acceleartion to be negative, that means the Velocity has to Decrease. (where Delta Velocity is change in Velocity or V2 - V1)
Differentiate positive acceleration and negative acceleration?
A positive acceleration is a change in velocity such that the latter velocity is greater than the former velocity and is therefore going fasterwhile a negative acceleration or deceleration is a change in velocity such that the latter velocity is lesser than the former velocity and is therefore going slower.Now let us look at the equation of a uniform acceleration (the change in velocity is uniform):a = (vf-vi)/sIf the final velocity is greater, you will have a positive acceleration. If the initial velocity is greater, you will have a deceleration.
Can velocity speed up an object?
Well velocity is basically the same thing as speed but with direction (velocity can be negative or positive and speed is always positive). l velocity l = speed So a change in velocity means a change in speed.
What does the negative portion of a velocity vs time graph mean?
Negative velocity usually means going in the opposite direction (i.e. reverse or backwards).

What is an example of a negative rate of change?
a car braking is a negative rate of velocity change
What is negative accelertion?
Acceleration is any change in velocity. Negative acceleration is when the change is such that the speed decreases.

How would you describe the values for acceleration?
positive or negative change of velocity or change of direction of the speed vector
Can a car have negative velocity and negative acceleration?
It cannot have negative velocity, it can have negative acceleration.
What is the rate of charge of velocity?
I think you mean the "rate of CHANGE" of velocity. (If you don't, then the question is meaningless.) The rate of change of velocity is called " acceleration ".
Can an object's acceleration be a negative number?
Yes it can be.When a body has its initial velocity greater than its final velocity, then the body can have negative acceleration since acc.=change in velocity/time
What does delta velocity mean?
"Delta" anything is scientific shorthand for "the change in". Delta-vee is the change in an object's velocity.
