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
