**drwls**, Tuesday, January 6, 2009 at 7:20pmIn a statics problem (in which an object is stationary or has constant velocity), the net force vector is zero. That means the sum of the force components in any direction is zero. In a dynamics problem, the net force equals mass times acceleration.

That is how all such problems are solved. Provide a specific problem if you need further assistance.

**Juanairis**, Tuesday, January 6, 2009 at 7:33pmone problem is

(if i am pushing a 20kg box at an acceleration of 2m/s squared,what net force am i using?)

....i just don't understand how to solve this problem...

**drwls**, Tuesday, January 6, 2009 at 7:59pmUse F = m a, which is Newton's second law

20 kg x 2 m/s^2 = 40 Newtons

(That is about 10 pounds of force)
