Want this question answered?
Not necessarily. Changing direction does affect the velocity, which is acceleration and direction combined.
The acceleration will either speed up or slow down an object's motion in the direction it is applied. Any change in speed or direction is considered acceleration.
Acceleration is defined as the change in velocity, and is a result of a force being applied on the object in question. Acceleration will not always result in an object changing direction, but it is capable of it (in the case of centripetal acceleration, all it does is change the direction.) Acceleration is a vector, therefore a direction must always be given when a value is stated.
Yes. Acceleration is a change in velocity. As velocity is a vector (direction and speed) changing either the speed or direction will change the velocity and thus be an acceleration (or decelleration)
Direction.

The moon's acceleration is expressed as a change in direction.
A change in speed (and/or direction) is acceleration.
acceleration in a direction that is not parallel to the direction you are moving
It can change the direction of motion or it can speed up or slow down an object.
Examples of acceleration are change in speed, change in direction, or both.

'Acceleration' is a change in the speed and/or direction of motion.
