Physics for IGCSE & O level - Forces And Motion (Section 10 - No. 23)

What is the relationship between force and mass, according to Newton's Second Law?

Force and mass are inversely proportional.

Force is independent of mass.

Force is directly proportional to mass.

Force and mass are equal.

Newton's Second Law: Force = mass x acceleration. If acceleration is constant, force is directly proportional to mass.
