Question

a body moving with a constant speed does not necessarily have a constant velocity give reason​

Answer 1

Explanation:

Because speed is scalar quantity whereas velocity is vector quantity. suppose a body is moving in a circular path with constant speed but it is not moving with constant velocity because we have not known the direction of body where it moves.

Hope it helps you

Answer 2

Here, body is moving with constant velocity.

To change its direction of motion, an external force must act in the direction opposite to the velocity, so given statement is false.
