According to Newton's Second Law, what happens when an unbalanced net force acts on an object?

In the context of Newton's laws of motion, what is the definition of the net force acting on an object?

In Newtonian mechanics, how is the net force on an object defined?

According to Newton's first law, if the net force on an object is zero ($F{n}_{e}t=0$), which statement must be true about its motion?

In the context of Newton's First and Second Laws, what is the definition of the net force acting on an object?

According to Newton's Second Law, $a=\frac{F}{m}$, one way to increase the acceleration of an object is by:

Newton's First & Second Laws: What happens when a net (unbalanced) force acts on an object?

According to Newton's Second Law, the net force on an object depends on both its mass and acceleration. Which equation correctly expresses this relationship?

In the context of Newton's Second Law, which expression correctly gives the net force on an object of mass $m$ accelerating at $a$?
