True or false? an object can be accelerating even if its speed is constant?

True. Acceleration is change in velocity, which is both speed and direction.. If an object is moving at a constant speed but changing directions (for example, constant circular motion) it is accelerating.True or false? an object can be accelerating even if its speed is constant?
True. Centripetal motion.





Force = Mass * Acceleration





Force also equals mv^2 / r





Velocity is constant, but a force is still being produced, thusly there is acceleration.True or false? an object can be accelerating even if its speed is constant?
False, by definition. But if by ';speed';, you actually mean ';velocity';, then true. Previous response is correct.
I learned about that and its FALSE
