F1 = F2
search around on http://www.glenbrook.k12.il.us/GBSSCI/PHYS/CLASS/newtlaws/u2l1b.html it helped me a whole lot with science hw.
When forces are unbalanced, an object will accelerate in the direction of the greater force. This acceleration will continue until the forces become balanced or until there is a change in the external forces acting on the object.
If the net force is zero, then the forces are balanced. If the net force is not zero, then the forces are not balanced. You can have a balanced pair of forces, but not a pair of balanced forces.
You say that the two forces are in equilibrium.
Unbalanced forces is when the forces are 0N or more. Balanced forces are 0.
If the forces are balanced, then by definition the sum of the forces is zero.
Balanced forces do not alter the motion of objects.
balanced
A balanced group of forces has the same effect as no force at all.
Balanced forces acting on an object do not change the object's position.
If the freezer is stationary, the forces acting on it are likely balanced. The gravitational force pulling it downward is likely balanced by the normal force exerted by the floor, as well as any frictional forces that may oppose its motion. If the freezer is accelerating or moving, the forces may not be balanced.
What two forces? If two forces go in opposite directions, and have the same magnitude, they will be balanced. Otherwise they wont'.
