How do you find net force?

Answer 1

(a= acceleration; Fnet= Net Force; m=mass)

Fnet=m*a

Net force is the sum of all forces acting on each other and it's unit's are expressed in Newtons=N

If two forces are going excatly oposite each other the two forces would be subtracted to find the Net Force. If the two forces are acting in the same direction the sum of the two forces would equall the Net Force.

Answer 2

When adding multiple vectors, you want them in vector form using i, j, k notation. You can then add like components (adding all the forces in the x,y and, z direction). That will give you the net vector in vector form which is plotted will give you the direction.

Answer 3

You select any two axes which are not parallel - usually they are taken to be mutually perpendicular. One of them is labelled the x direction and the other is the y direction. If a force of magnitude M newtons makes an angle of k degrees with the x dierction, then the component of that force in the x direction [the x component] is M*cos(k). If the same force makes an angle j with the y derection, then the y component is M*cos(j). If the two axes are perpendicular then j and k are complementary angles so that cos(j) = sin(k) and so the y component is M*sin(k).

Answer 4

To find the net force acting on an object, you need to consider the individual forces acting on the object. Add up all the forces acting in the same direction and subtract the forces acting in the opposite direction. The net force is the overall force that results from this calculation.
