Can body moving at constant speed have acceleration? justify​

Answer»

Yes. Acceleration is any change in velocity. Velocity is a vector QUANTITY because it  includes both speed and direction. Speed is a scalar quantity and does not INCLUDE  direction. Therefore, if your motion is changing direction, then you have a changing velocity  regardless of your speed. And a changing velocity means you have acceleration.Explanation:Acceleration  =  Rate of change in Velocity Velocity has two component Magnitude & direction If it is moving with constant speed then its magnitude is constant (speed is constant) but its direction Can change There WOULD be acceleration as there would be change in direction. In Circular Motion - even if it is moving with constant speed the direction is changing CONTINUOUSLY so there is ANGULAR acceleration   if there is no change in direction & Speed of object then acceleration would be zero ( No acceleration)  HOPE IT HELPS !!!
