# Newtons Second Law

1. Jan 20, 2010

15. Newton’s second law of motion states that
A. the acceleration of an object is a ratio of the net force over its mass
B. forces always act in pairs
C. for every action there is an equal but opposite reaction
D. the inertia of an object is inversely proportional to the object’s mass
(for this I supposed that that the equation f=ma for newtons second law could be expressed as a=f/m)
