Question

10 newtons second law states that a a force is needed to keep an object moving. b the acceleration of an object is proportional to the net force exerted on the object and inversely proportional to the mass of the object. c objects remain either at rest or continue moving in a straight line with constant speed only if the net force on that object is zero. d all forces come in pairs.

Explanation:

Newton's second - law is expressed as $F = ma$, where $F$ is the net force, $m$ is the mass and $a$ is the acceleration. It shows that acceleration is proportional to the net force and inversely proportional to the mass. Option A is related to Aristotle's wrong view. Option C is Newton's first law. Option D is Newton's third law.

Answer:

B. the acceleration of an object is proportional to the net force exerted on the object and inversely proportional to the mass of the object
