Hey there! My name is Christy and I'm gladly to help you out!
The three main forces that stop moving objects are friction, gravity and wind resistance. Equal forces acting inopposite directions are called balanced forces. Balanced forcesacting on an object will not change the object's motion. When you add equal forces in opposite direction, the netforce is zero.
Hope this helped!
I think it would be the scientific method.
