Is it possible for an object to accelerate but without changing its speed?
A) Yes, for example when a car is halfway up a straight hill [a hill whose slope, or angle with the horizontal, does not change] and moving a an unchanging speed.
B) Yes, for example when a car turns a corner while maintaining an unchanging speed.
C) Both of the above.
D) No, because the word "acceleration" means "a change in speed."
