The two forces acting on your body are the weight and the normal force
Explanation:
As you sit on your chair in front of the computer, there are 2 forces acting on you:
- The force of gravity, of magnitude [tex]mg[/tex] (where m is your mass and [tex]g=9.8 m/s^2[/tex] is the acceleration of gravity), acting downward
- The normal reaction exerted by the chair on your body, N, acting upward, and balancing your weight
We can apply Newton's second law to this situation; the law states that the net force acting on an object is equal to the product between the mass of the object and its acceleration:
[tex]\sum F = ma[/tex]
where
[tex]\sum F[/tex] is the net force
m is the mass
a is the acceleration
For your body sitting on the chair,
[tex]\sum F = N-mg[/tex]
we also know that your body is at rest, so the acceleration is zero:
[tex]a=0[/tex]
This means that the net force is zero, and therefore:
[tex]\sum F = 0 =N-mg\\\rightarrow N = mg[/tex]
