Asked in Gravity
When gravity is pulling you downward when you sit is this balanced or unbalance force?
Force equals mass times acceleration, if you are sitting at rest you are not accelerating, so your acceleration is zero.
The force is your mass times zero, 75 kg x 0 ms-2= 0 newtons.
If the force is zero, this means the force of gravity pulling you down is cancelled out by the force of the chair pushing you up.
So the forces are balanced.
