centripetal acceleration must be considered.
dont forget gravity!
If the car is going at a constant speed of 100 km/h, then its acceleration is zero. Acceleration measures the rate of change of velocity, and since the car's speed is not increasing or decreasing, there is no acceleration.
Yes, when you go around a corner on a bicycle, you are changing your direction of motion, which requires centripetal acceleration towards the center of the curve. This acceleration allows you to turn without skidding off the curve.
a horizontal line
Not necessarily so. Negative (deceleration) could be growing or decreasing in magnitude. The cause is going to be the Force that is acting on the system. If the Force is increasing, the acceleration will be also.
At a constant speed there is no acceleration. Acceleration describes a positive change in speed meaning to go faster. Deacceleration describes how fast something is slowing down. But at a constant speed of 60mph there is acceleration or deacceleration.

Yes, it it's going round in a circle, for example.

The graph of acceleration vs time for something going at a constant positive velocity would be a horizontal line at zero on the acceleration axis. This is because there is no change in velocity, so the acceleration is constant and equal to zero.

Acceleration is the change in velocity. Velocity is the change in speed or direction. Therefore, acceleration is changing the change in speed or direction. So if you are going at 50mph and then you are going at 55mph and then at 60mph, your acceleration is constant at 5 mph. if the change in accleartion is changing, then it is not constant. If you turn dirctions even while you move at a constant velocity, you are accelerating.
The acceleration vs. time graph for something moving at a constant positive velocity will be a horizontal line at zero acceleration. This is because acceleration is the rate of change of velocity, and if the velocity is not changing (constant), then the acceleration is zero.
Acceleration is the rate of change in velocity (speed) Thus if your speed is constant (50 miles per hour) your acceleration is zero
