Either of these is referred to as positive acceleration:
A) the object's velocity is increasing in the frame of reference
B) the object is being moved in a positive direction in a coordinate plane

When is acceleration of an object positive?
When its speed is increasing
Does acceleration have a negative or positive value if the velocity is increasing speed?
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
Is it possible for a falling object to have a positive acceleration?
If you define the positive direction as pointing down, then the falling object has positive acceleration.Its magnitude is 9.8 m/s2.
When a car's velocity is negative and its acceleration is positive what is happening to the car's motion?
The car is slowing down
An object with constant velocity has positive acceleration?
Answer This occurs when an object istraveling in one direction but has an acceleration in the opposite direction, which means it is decreasing in speed. For a given period of time, the speed has decreased. Acceleration is the change of velocity per second. T1 = 5 seconds V1 = 100mph T2 = 10 seconds V2= 50 mph Acceleration = (V2 - V1 ) / (T2 - T1) = (50-100)/(10-5) = -10 ft/sec/sec Positive(+) acceleration means an object will be going faster over an interval of time.

How can an object slowing down have an acceleration that's not negative?
If the positive direction was defined at the outset as the direction opposite to the direction in which the object happens to be moving just now, and the object is slowing down, then the acceleration is positive because, algebraically, the object's speed is increasing in the positive direction.
What undergoing acceleration does an object change its speed from 10 ms to 3 ms?
Positive acceleration!(:
Is it possible for a falling object to have a positive acceleration?
If you define the positive direction as pointing down, then the falling object has positive acceleration.Its magnitude is 9.8 m/s2.
When a car's velocity is negative and its acceleration is positive what is happening to the car's motion?
The car is slowing down
Can an object's rate of acceleration decrease and its speed increase at the same time?
Yes, assuming the object's rate of acceleration remains positive during the time it is decreasing.

The car is slowing down
As a freely falling object speeds up what is happening to its acceleration due to gravity?
Its acceleration due to gravity is constant. The acceleration is equal to the object's change in speed every second. I've tried to illustrate the constantly-increasing falling speed in my diagram below.
