Question

An object with constant velocity has always constant speed Why?

Answer 1

Answer:

To have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion to a straight path. Newton's second law (F=ma ) suggests that when a force is applied to an object, the object would experience acceleration.

Answer 2

Answer:

velocity is nothing but the speed with constant ditection.speed has no direction while velocity has direction
