  2. Net Force • a combination of all of the forces acting on an object. • Forces in the same direction are added • Forces in opposite directions are subtracted.

  3. Balanced Forces • if there is a net force of zero, then the forces are BALANCED. • Balanced Forces do NOT change the motion of an object. (Doesn’t start or stop moving).

  4. Unbalanced Forces • if the net force is NOT zero, then the forces are UNBALANCED. • Unbalanced Forces cause the motion of an object to change. (Starts or stops moving, or changes direction).

  5. Newtons (N) • unit of force • 1N= 1kg · m/s2 • measure with a spring scale
