1. We have an intuitive idea of what a "force" is. We may think of a force as a

2. That is the very ________________________that is described by Newton's First Law. An object
continues in motion simply because it was in motion if there are no forces acting on it to change its

3. A force of _________ unit will give an object of 1.0 kg mass an acceleration of 1.0 m/s/s ; this
force is known as: ONE NEWTON (1.0 N) 1 N = ( 1 kg ) ( 1 m/s/s )

4. A surface can always supply a ___________force, perpendicular to the surface. However, a
surface quite often also supplies a fiction force parallel to the plane. Friction forces always oppose
the motion -- or prevent the motion.
