An object in motion needs less force
to continue moving because the inertia or the resistance to change in motion
was already overcome and the sliding friction that opposes a moving object is
also lesser. Therefore, <span>it is easier to
move an object at constant velocity as you only need to overcome the resisting
forces of the object.</span>
<span>physical agents are mechanical forces that produce injury or tissue trauma. some examples of this are extremes of temperature (burns and really deep cold), sudden changes in atmospheric pressure, radiation, and electric shock.</span>
