Question

can body moving at constant speed have acceleration? justify​

Answer 1

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)
