Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In order to be ____ forces, their effects must cancel each other out and not cause a change in an object’s motion.
A
balanced
B
strong
C
weak
D
normal
Explanation: 

Detailed explanation-1: -When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged.

Detailed explanation-2: -When forces are balanced, they cancel each other out, resulting in no change in motion for the object they are acting on. Unbalanced forces do not cancel each other out, and result in a change in motion for the object they are acting on.

Detailed explanation-3: -If all the forces pushing an object cancel each other out, the object does not move. We call this being balanced.

Detailed explanation-4: -Balanced forces do not cause a change in motion. If the people on each side of the rope are pulling with the same strength, but in the opposite direction, the forces are balanced. The result is no motion. Balanced forces can cancel each other out. Any time there is a balanced force, the object does not move.
