Question

choose the correct answer
which is not true of balanced forces?
balanced forces will cause the motion of an object to increase.
balanced forces are two equal forces pushing against each other on an object.
balanced forces do not cause a change in the motion of an object.

Explanation:

To determine which statement about balanced forces is not true, we recall the definition and effects of balanced forces. Balanced forces are equal in magnitude and opposite in direction, so their net force is zero. A net force of zero means there is no change in the object's motion (either it remains at rest or continues moving at a constant velocity).

• The statement "Balanced forces are two equal forces pushing against each other on an object" is true as balanced forces have equal magnitude and opposite direction.
• The statement "Balanced forces do not cause a change in the motion of an object" is true because the net force is zero, so there's no acceleration (and thus no change in velocity or direction).
• The statement "Balanced forces will cause the motion of an object to increase" is false because an increase in motion (acceleration) requires a net force, and balanced forces have a net force of zero.

Answer:

Balanced forces will cause the motion of an object to increase.
