Can something with constant speed accelerate?

Answer

Yes, something with a constant speed can be accelerating. Speed is a scalar quantity, meaning that it does not factor in direction. Acceleration is a vector quantity and therefore includes direction. An object moving in a circular pattern, for example, can remain at the same speed and be considered to be accelerating at the same time.
