What is the effect on accelerationif we decreasing velocity?
If you are decreasing velocity, you are undergoing negative acceleration.
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.
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)
What is the change in velocity per unit time?
Acceleration.
In what ways is a bouncing ball accelerating?
-- On the way down, its speed is increasing, which is a change in velocity, i.e. an acceleration. -- At the bounce, its direction changes, which is a change in velocity, i.e. an acceleration. -- On the way up, its speed is decreasing, which is a change in velocity, i.e. an acceleration.
What is the effect on accelerationif we decreasing velocity?
If you are decreasing velocity, you are undergoing negative acceleration.
When acceleration increase does velocity increase?
No. Acceleration IS a change of velocity - any change. When velocity increases, there IS acceleration. The acceleration itself may be increasing, decreasing, or remain constant.
Why does the slope of a velocity time graph give you acceleration?
if there is a slope, the velocity is either increasing or decreasing. This is acceleration.
What is called negative accelarration?
Deceleration. Negative acceleration = Velocity is decreasing by time. Positive acceleration = Velocity is increasing by time. Zero acceleration = Velocity is the same by time.
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.

For Acceleartion to be negative, that means the Velocity has to Decrease. (where Delta Velocity is change in Velocity or V2 - V1)
Does an object experiencing a constant velocity have a zero or non-zero value for acceleration?
If an object is sustaining a constant velocity it has 0 acceleration, because acceleration is either increasing or decreasing speed.
Is an object that is slowing down accelerating?
Acceleration is defined as change of velocity so the answer to the question is yes. Negative acceleration (ie when velocity is decreasing) is called deceleration.
What is the change in velocity per unit time?
Acceleration.

When object moves upwards what is the velocity and acceleration?
When an object is moving upwards, its velocity is directed upwards. If the object is near the Earth or any other planet, then its acceleration is directed downwards, which also means that its upward velocity is decreasing.
The speed of a car moving on a straight road is decreasing on applying the brakes its velocity and acceleration are in same direction?
By convention, yes, but the acceleration is negative
