Question

when scientists want to represent a force, they use an arrow drawn to a certain to show the size and direction of the force. they make up a scale and draw the arrow to the correct length according to the scale. for example, a scientist may want to represent a force of 30 n to the right. the scientist will make a scale that shows that 1 cm represents 10 n, then draw the arrow exactly 3 cm long, and put the arrowhead pointing to the right. if no scale is given, longer arrows are understood to represent greater forces. 1 cm = 10 n. what happens to an object when the forces acting on it are balanced? nothing. the motion of the objects change

Explanation:

According to Newton's first - law of motion, when the net force acting on an object is zero (forces are balanced), the object's motion does not change. It will either remain at rest if it was initially at rest or continue to move with a constant velocity if it was in motion.

Answer:

The motion of the object does not change.
