You are confusing terms.
An acceleration is a change in velocity not necessarily an increase in velocity, it is a change.
A change in velocity is brought about by a force acting upon a body.
There are several terms for the time derivative of acceleration. Jerk is probably the most common, but jolt, surge, and lurch are also sometimes used.
positive acceleration
Acceleration is the rate of velocity change.
positive acceleration
Since velocity is a vector, it's confusing to state that it "increases". It's absolute value (i.e., the speed) can increase or decrease.
" speeding up "
If your acceleration is increasing then by default your velocity has to increase. Acceleration = velocity/time so if acceleration is increasing the velocity is also increasing... And just for fun, just as the change in distance is velocity, and change in velocity is acceleration with respect to time, the change in acceleration with respect to Time is called a jerk
Acceleration.
It velocity is constantly increasing, v=vo + at.
Velocity basically means how fast you are going. Acceleration means how much your speed is increasing. So if there is zero velocity that means the object is not moving. If there is zero acceleration, that means that the speed is not increasing but there is actual speed and the object is not increasing it's speed what ever that may be.
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)

Deceleration. Negative acceleration = Velocity is decreasing by time. Positive acceleration = Velocity is increasing by time. Zero acceleration = Velocity is the same by time.
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.
when velocity of a car is increasing then velocity and acceleration are parallel to each other.
Acceleration.
By definition acceleration is the change in velocity (speed).
if there is a slope, the velocity is either increasing or decreasing. This is acceleration.
It velocity is constantly increasing, v=vo + at.

If there is zero acceleration, that means that the speed is not increasing but there is actual speed and the object is not increasing it's speed what ever that may be.
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
if 'S' is diplacement and 't' is time: dS/dt=V (velocity) dV/dt=a (acceleration)
Concave up. "Acceleration is increasing with time" tells us that the derivative of acceleration is positive. Since acceleration is the derivative of velocity, this means that the second derivative of velocity is positive. By definition, having a non-negative second derivative means that velocity is concave up.
