Question

an object in motion will stay in motion unless acted upon by what type of force?
balanced
electrical
magnetic
unbalanced

Explanation:

According to Newton's first - law of motion, an object in motion will stay in motion with a constant velocity (in a straight line) unless acted upon by an unbalanced force. Balanced forces result in no change in motion. Electrical and magnetic forces are specific types of forces, but the general principle here is about unbalanced forces causing a change in the object's state of motion.

Answer:

D. unbalanced
