Question

Assertion: An object can have
constant speed but variable
velocity
Reason: Speed is a scalar but
velocity is a vector quantity. [1]
(1 Point)​

Answer 1

Answer:

Assertion and reason is true but the reason is the not the right explanation for the given assertion.

Explanation:

Consider a circular motion with an object moving with constant speed of 5 km/h,

The speed remains 5 km/h

But velocity is velocity is speed with direction so as the direction of the object changes in a circular motion the velocity changes. 5 km/h north then 5 km/h south etc.

Answer 2

Answer:

becouse the object are moving is constant speed and the variable is velocity therfor. therfor velocity = distance/time therfor vector quantity is velocity ,acceleration ,desplacement therfor object move constant speed the speed = acceleration / time therfor acceleration = displacement /time then the object are move one pogetion to another pogetion hence the object velocity is veactor quantity
