In that case, the speed will increase.
acceleration=ratio of change in velocity in a specific direction to time. speed=ratio of distance to time.
Acceleration is the rate of change of VELOCITY, not of SPEED. If the velocity changes, there is acceleration. It is enough for the direction to change.
"Constant" means that regardless of when you measure it, the result is always the same. "Velocity" means speed and its direction. "Acceleration" means the rate at which speed is changing, and the direction in which it's changing.
Speed is (distance covered) divided by (time taken to cover the distance).Velocity is a speed and its direction.Acceleration is any change of velocity.
acceleration is change in velocity over time. It is important to know that speed is not a vector quantity; it is scalar (meaning it does not have direction), -- velocity does. Therefore, speed is only the MAGNITUDE of velocity. Also, acceleration is a vector quantity meaning it has both magnitude and direction. If you change EITHER magnitude or DIRECTION, acceleration changes. Okay anyway to answer your question, You can have the same magnitude of velocity (aka same speed) and still be accelerating if YOU CHANGE DIRECTION. --- gh

The acceleration is the same direction of the velocity

No. Acceleration only affects velocity in one particular direction (same direction as acceleration). Speed is the summation of velocities in all directions.

Velocity is speed in a certain direction. You can keep speed the same, and if you change direction then you have changed velocity.
It's not. If you speed is constant (but not zero), then your velocity won't be zero, either.You may be confusing this with the following: If your VELOCITY (not your speed) is constant, then your ACCELERATION is zero. Acceleration refers to how quickly velocity changes, so if velocity doesn't change at all, acceleration is zero.
velocity (v) = initial velocity (v0) + acceleration (a) x time (t); that is v = v0 + at. The relation is the same for speed ( a scalar) which is velocity ( a vector) without direction assigned; velocity = speed
Any falling object has acceleration and velocity vectors in the same direction.
No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.
