Problem: Newton's First Law
Newton's First Law of Motion says that, in the absence of external forces, an object at rest stays at rest and an object in motion continues at constant velocity.
a) If no forces act on a stationary object, can it start to move?
b) If no forces act on a moving object, will it slow down?
c) If no forces act on a moving object, can it turn?
