Newton’s Second Law-if an unbalanced force acts on a body, it is accelerated by an amount proportional to the unbalanced force and in the samedirection but inversely proportional to its mass.maF=Where:F - force (N, dynes)m - mass (kg, g)a – acceleration (m/sec2, cm/sec2) Dynamics of Translation-a study of motion and the forces causing the motion.Sample Problems1.A constant horizontal force at 40N acts on a body on a smooth horizontal plane. The body starts from rest and is observed to move 100m in 5 sec. What is the mass of the body?
