Chapter 4-3 Newton’s 2nd and 3rd Laws

Newton’s 2nd Law Force is proportional to mass and acceleration. Force = Mass x Acceleration (F=ma) A = (Vf – Vi)/time

Newton’s 3rd Law Forces always exist in pairs. Every action has an equal and opposite reaction.

Practice 4B #1. The net external force on the propeller of a 3.2 kg model airplane is 7 N forward. What is the acceleration of the plane? Knowns? m = 3.2, F = 7 Unknown? a = ? Equation? F=ma Answer? 7 = 3.2a, a = 2.2 m/s2 Forward (vector – need direction)
