A body can have constant speed but still accelerate as in case of uniform circular motion.
In uniform circular motion speed remains constant and direction of velocity changes with every point in the direction of tangent drawn from that point. Therefore Speed remains same but velocity varies making the body accelerate.
A body performs an accelerated motion, with uniform speed. The motion ...
Explanation:
When a body performs an accelerated motion with uniform speed, its motion is circular. The reason behind it can be explained in the following points:
Uniform Speed:
Uniform speed means the body is moving with a constant speed. It means that the magnitude of the velocity of the body is constant. The direction of the velocity vector can be changed, but the magnitude of the velocity remains constant.
Accelerated Motion:
Accelerated motion means the velocity of the body is changing with time. It means that the magnitude of the acceleration of the body is not zero. The direction of the acceleration vector can be changed, but the magnitude of the acceleration is not zero.
Circular Motion:
Circular motion is a kind of motion in which a body moves in a circular path. In circular motion, the direction of the velocity vector changes continuously, but the magnitude of the velocity remains constant. The direction of the acceleration vector also changes continuously, but the magnitude of the acceleration is not zero.
Conclusion:
When a body performs an accelerated motion with uniform speed, its motion is circular. In this case, the magnitude of the velocity of the body remains constant, but the direction of the velocity vector changes continuously. The magnitude of the acceleration of the body is not zero, and the direction of the acceleration vector also changes continuously. Hence, the motion of the body is circular.
