+229 acceleration is the change of speed and / or direction of an object.
true or false
+219 This could be true because acceleration is the change in speed of an object which could change the direction of the object. But velocity is very similar to acceleration and velocity is changes in speed. So the answer might be true.
Hope this helps ;P
+37146 'Speed' is a component of velocity....if you change 'speed' you change velocity
The other component of Velocity is DIRECTION....if you change direction, you change velocity....
A change in velocity over time is acceleration
So TRUE.
