Sir Isaac Newton was among the first to observe the movement of objects and express those observations as laws. According to Newton's law of inertia, a body
a. in variable motion will remain in motion unless its state of matter changes.
b. with no kinetic energy will remain along a path with a constant radius.
c. with a variable potential energy will remain with a constant, nonzero acceleration.
d. in uniform motion will remain in motion unless it is acted upon by an outside force
Newton's first law of motion states that a body at rest remains at rest or if in motion remains in motion at a constant velocity unless acted upon by a external Force
