A block slides down a frictionless incline. As it slides, the block continually accelerates. Is a force doing work on it? Is its total energy changing?

(A) No; No

(B) Yes; Yes

(C) Yes; No

(D) No; Yes

I do know that a force is doing work on it since it accelerates, but I do not understand whether its total energy is changing....
