Objects in motion tend to stay in motion in a straight line at a constant velocity unless acted on by a(n) force

Newton's first law of motion

Explanation:

Newton's first law of motion states that an object will continue to remain at rest or move with uniform motion unless it is acted upon by an external force.

This law is known as the law of inertial.

Unless a net force greater than zero acts on a body, it will continue to remain at rest or move uniformly.

This is very correct and has a wide range of application for many mechanics studies. In that we know that an object can only change motion or accelerate by adding external force to act on it.

the correct answer is b

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper
