If we have a body traveling in void with a constant velocity, and a powerful gravity source suddenly appears in the backside of the body (such that the gravity opposes the velocity of the object), thus suddenly stopping the object by exerting a gravitational force on it, will the kinetic energy of the body be turned into heat?

Please detail your explanation.
