4-2 Force, Mass, And Acceleration

Force, Mass, and Acceleration Chapter 4, Section 2

Newton’s Second Law of Motion The net force acting on an object is equal to the product of its acceleration and its mass  Force = Mass x Acceleration  Acceleration is meters per second (m/sec)  Mass is measured in kilograms (kg)  Force is measured in kg x m/sec2 (Newtons) 

Increase in Force causes an Increase in Acceleration Increase in acceleration causes an Increase in Force Force and Acceleration have a DIRECT relationship Increase in Mass causes a decrease in Acceleration Decrease in Mass causes an increase in Acceleration Mass and Acceleration have an INDIRECT, or inverse relationship
