Question

a probe traveling through outer space is moving at a constant velocity. which statement applies to the motion of this probe? a an unbalanced force is acting on the probe, causing it to accelerate. b the probe will continue on its current path until an unbalanced force acts on it. c the probe will undergo constant acceleration until a force acts on it. d the force that makes the probe move through space is equal to its mass divided by its velocity

Explanation:

Step1: Recall Newton's first law

An object in motion will stay in motion with a constant velocity (in a straight - line path) unless acted upon by an unbalanced force.

Step2: Analyze each option

• Option A: If an unbalanced force acts on the probe, it will accelerate. But the probe is moving at a constant velocity, so no unbalanced force is acting on it currently.
• Option B: This is in line with Newton's first law. Since the probe is moving at a constant velocity, it will continue on its current path until an unbalanced force acts on it.
• Option C: The probe is moving at a constant velocity, so there is no acceleration.
• Option D: Force is equal to mass times acceleration ($F = ma$), not mass divided by velocity.

Answer:

B. The probe will continue on its current path until an unbalanced force acts on it.
