Name that Newtonian law.

Question

Newton: egomaniac or troubled genius? – Physics World

You exert a net force of 4 N to the right on an object with a mass of 8 kg, the object will accelerate at 0.5 m/s2 to the right.

a
Newton's First Law of Motion
b
Newton's Second Law of Motion
c
Newton's Third Law of Motion

Answer 1

The scenario you've described corresponds to b) Newton's Second Law of Motion.

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is mathematically expressed as \( F = ma \), where \( F \) is the net force, \( m \) is mass, and \( a \) is acceleration. In your case, a net force of 4 N acting on an 8 kg object resulting in an acceleration of 0.5 m/s² fits this law perfectly.
