Under all conditions within human experience. That is, all non-relativistic conditions.
there is no acceleration if the body is moving with constant velocity
If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.
The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.
Mass of a body is constant
Both the mass and the weight of your body increase. But if you're inside a spaceship, the mass of the spaceship remains constant.
why the human body temperature always remains constant in normal person
no it does not remain contant.
Under normal conditions your blood remains inside your body, and no one sees it. If you are bleeding, then anybody who happens to be there may see it.
If it remains at constant speed then it can be considered to be in equilibrium.
Newton's first law of motion states that a body at rest remains at rest and a body in motion remains in motion at constant velocity in a straight line unless acted upon by an unbalanced force.
The body maintaining relatively constant conditions within the body.

Negative feedback.
A body can have a constant speed yet a nonzero acceleration when it is in a circular motion because though it is having a constant speed but the direction in which it is moving keeps changing at each instance and since acceleration is a vector quantity,it becomes non-zero.
either remain unchanged or keep a dynamic balance that remains constant.
