Acceleration is the change in an ogjects speed or a change in an objects direction of motion or both of these. If instead of speed you use the word velocity , which is both an object's speed and its direction of motion, then you could say "acceleration is the change in an objects velocity" and that would cover all the possibilities in one statement.
It involves the change in velocity, which is a vector quantity, meaning that it is also the change in speed.
speed or direction or both
A change in the velocity is produced by a force acting on the object. A change in velocity means a change in speed or direction (or both).
This is one definition of acceleration (including deceleration) - any change in the speed of motion of a moving object, or in the direction of its motion. Motion is a vector value with both speed and direction.
It doesn't. For example, you can go in a straight line, and speed up or slow down, without changing direction. And if there is both a change in direction and a change in speed, the change of speed wouldn't be the CAUSE for a change in direction. (On the other hand, both can be caused by a force applied to an object.)
Change of speed or direction or both of an object.
Speed or direction or both.
Both.

Examples of acceleration are change in speed, change in direction, or both.
speed or direction or both
Acceleration by definition is a change in speed, direction, or both. If the speed is constant, the direction could still be changing. You can feel a change in direction, therefore you can feel acceleration even if the speed is constant.

Yes. Acceleration by definition is a change in speed, direction, or both. If the speed is constant, the direction could still be changing. You can feel a change in direction, therefore you can feel acceleration even if the speed is constant.
