The definition of acceleration is: Any change of velocity, that is, speed
or direction of motion.
If an object is undergoing constant acceleration, then the definition says
that its velocity must be changing.
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.
Acceleration is constant.
If the acceleration is constant, yes. However, the acceleration of an object can vary. The rate of change of acceleration is called jerk.
Acceleration is any change in velocity. Velocity is made up of a magnitude (the speed), and a direction. Velocity can change if the speed increases, if it decreases, or if the direction changes. For example, when a car goes around a curve, you feel the force of the acceleration.

There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
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.
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.

If the acceleration is constant, yes. However, the acceleration of an object can vary. The rate of change of acceleration is called jerk.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
Acceleration is any change in velocity. Velocity is made up of a magnitude (the speed), and a direction. Velocity can change if the speed increases, if it decreases, or if the direction changes. For example, when a car goes around a curve, you feel the force of the acceleration.
acceleration
if the velocity is constant, the acceleration is zero. The acceleration is the rate at which the velocity changes, so if it stays the same, the car isn't accelerating.
