It sounds as if you're looking for an equation that will tell you that number. Thereason you haven't found it yet is that there's no such equation.The effect that force has on a moving object is to 'accelerate' it ... change thedirection it's moving, slow it down, speed it up, etc. ... only depending on thedirection of the force compared to the direction of the motion.If you want to stop a moving object, you apply a force to it opposite to the directionit's moving. It makes no difference how large or small the force is. As soon as it startsacting on the object, the object begins to slow down, and you only have to wait for itto stop. Of course, the larger the force is, the sooner the object stops. But in principle,you can stop an asteroid with the force of a feather, if you're willing to wait long enough.There's no such thing as the amount of force 'needed' to stop the object.

force can change the shape and size of an object force can change the direction of an moving object force can make a stationary object move and make a moving object move faster force can slow down or completely stop a moving object
The frictional force needed to just stop something from moving is called limiting friction, and the object is said to be in limiting equilibrium.
Any force will do, but the larger the force, the faster will the object stop. The force, of course, has to be applied in the direction opposite to the movement.

what starts to move an object is force because it's pushing on the object and what stop's the obect from moveing is force too because if the force is going the oppisit way its going to stop the object.

any force opposite the direction of motion
The frictional force needed to just stop something from moving is called limiting friction, and the object is said to be in limiting equilibrium.
When balanced forces are applied to a moving object, the object likely slow and eventually stop. How quickly that occurs depends on the amount of force.
A force or acceleration
Any force will do, but the larger the force, the faster will the object stop. The force, of course, has to be applied in the direction opposite to the movement.
An unbalanced force can: change the speed an object moves at change the direction an object is moving cause an object to start/stop moving
