Question

multiple choice question
newtons first law states that
o all forces come in pairs; the two forces in the pair act on different objects and the forces are equal in strength and opposite in direction.
o the acceleration of an object is inversely proportional to the net force acting on it and proportional to its mass.
o the acceleration of an object is proportional to the net force acting on it and inversely proportional to its mass.
o an object at rest will remain at rest, or continue to move in a straight line with constant speed, if and only if the net force acting on it is zero.

Explanation:

Newton's first law, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue to move in a straight line with constant speed, if and only if the net force acting on it is zero.

Answer:

an object at rest will remain at rest, or continue to move in a straight line with constant speed, if and only if the net force acting on it is zero.
