question 10 (1 point)
two pool balls collide head - on. at every moment during the collision, the magnitude of the force the first ball exerts on the second is exactly equal to the magnitude of the force the second ball exerts on the first. this is an example of
newtons first law.
newtons second law.
newtons third law.
newtons law of gravitation.

Explanation:

Newton's third law states that for every action, there is an equal and opposite reaction. In the collision of two pool balls, the force exerted by the first ball on the second (action) is equal in magnitude and opposite in direction to the force exerted by the second ball on the first (reaction), which matches the description. Newton's first law is about inertia, the second about force and acceleration ($F = ma$), and the law of gravitation is about gravitational attraction between masses, so they don't apply here.

Answer:

Newton's third law.
