Question

What happens to the motion of an object when the forces acting on it are balanced

the motion changes
the motion does not change
the motion speeds up.
the motion slows down.

Answer 1

When the entire group of forces acting on an object is balanced, the vector sum

of the forces is zero, and the effect of the group of forces on the object's motion

is identical to the effect of no force at all. The object continues in constant uniform

motion.

To state the outcome of the situation in three different ways:

-- The object's acceleration is zero.

-- The object's velocity is constant.

-- The object's speed and direction of motion don't change.

The direct answer to the question is: Nothing happens to its motion.
