Question

what what happens to the inertia of an object when the velocity is doubled

Answer 1

the mass of an object increases so does its inertia. ... Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum

Answer 2

Inertia is the property of mass that resists change. Therefore, it is safe to say that as the mass of an object increases so does its inertia. ... If you increase either mass orvelocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.
