That depends on the situation. If the object is moving freely in a vacuum, the speed stays the same. If an object is accelerating, the speed change depends in part, on the mass of the object.
An object that stays at rest, stays at rest and an object in motion stays in motion with the same speed and in the same direction, unless acted upon by an unbalanced force
It stays the same.
