newtons second law states that
all forces come in pairs; the two forces in the pair act on different objects and are equal in strength and opposite in direction.
the acceleration of an object is proportional to the net force acting on it and inversely proportional to its mass.
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.
the acceleration of an object is inversely proportional to the net force acting on it and proportional to its mass.

Explanation:

Newton's second law is \(F = ma\), where \(F\) is the net force, \(m\) is the mass, and \(a\) is the acceleration. This formula shows that \(a=\frac{F}{m}\), meaning acceleration is proportional to the net force and inversely proportional to mass.

• The first option wrongly states acceleration is inversely proportional to net - force (it should be directly proportional to net force as per \(a=\frac{F}{m}\)).
• The second option is about Newton's first law (an object at rest stays at rest or moves with constant velocity when net force is zero).
• The third option is correct as it aligns with \(a = \frac{F}{m}\) (acceleration proportional to net force \(F\) and inversely proportional to mass \(m\)).
• The fourth option is about Newton's third law (forces in pairs).

Answer:

The acceleration of an object is proportional to the net force acting on it and inversely proportional to its mass.
