Question

name the type of molion in which a body has uniform speed but not uniform velocity

Answer 1

HELLO THERE!

Speed is a scalar quantity, so it has only magnitude. If magnitude remains constant, the body is said to be moving with uniform speed.

Velocity is a vector quantity, so it has both magnitude and direction. If any one of the two is non-uniform, velocity becomes non-uniform.

In case of Uniform Circular Motion, a body moves with constant speed. However, at each point, the direction keeps on changing. Hence, the velocity is not uniform. So, in case of Uniform Circular Motion, the speed is uniform but velocity is not uniform.

THANKS!

Answer 2

Circular motion is the type of motion in which a body has uniform speed but no uniform velocity.

Velocity is a vector quantity, which means, it requires both magnitude as well as direction for its complete expression. In circular motion, the direction of velocity keeps on changing, though the magnitude (speed) remains uniform. As a result, the body has uniform speed but non-uniform velocity.
