Question

match each of newtons laws of motion to the statement it best describes. newtons first law of motion newtons second law of motion newtons third law of motion the less massive the sail is, the more it will accelerate for a given number of reflected photons. the sail exerts a backward force on the photon that is equal in magnitude to the forward force that the photon exerts on the sail. the sail will move at a constant velocity until photons are reflected off of it.

Explanation:

Newton's first law (law of inertia) states an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. The statement about the sail moving at a constant velocity until photons act on it fits this. Newton's second law ($F = ma$) relates force, mass, and acceleration. The statement about less - massive sail accelerating more for a given number of photons is related to this. Newton's third law states for every action, there is an equal and opposite reaction. The statement about the equal - magnitude forces between the sail and the photon is an example of this.

Answer:

Newton's first law of motion: The sail will move at a constant velocity until photons are reflected off of it.
Newton's second law of motion: The less massive the sail is, the more it will accelerate for a given number of reflected photons.
Newton's third law of motion: The sail exerts a backward force on the photon that is equal in magnitude to the forward force that the photon exerts on the sail.
