Question

What is the state of an object being acted upon by an unbalanced force? A. at rest B. zero speed C. in motion with a constant velocity D. accelerated E. any of these

Answer 1

Answer:

D. accelerated

Explanation:

According to Newton's first law of motion, an object always remains in its state of rest or in uniform motion until an external unbalanced force is acted upon the object. This means if an external unbalanced force is acted on the object, it will come to a non-uniform motion i.e., an accelerated motion.

Let me first get you clear that uniform motion is determined by a constant velocity and a state of rest is considered by a zero velocity or speed. But, here we have an unbalanced force acting on the object. This means the object will change its velocity and hence, it has an accelerated motion.
