Newton’s 2nd Law of motion Chapter 10 Newton’s 2nd Law of motion

Newton has Three Laws of Motion

FORCE = MASS X ACCELERATION Chapter 10 Main Ideas Details 2nd Law F=MA Newton’s Second Law – FORCE = MASS X ACCELERATION The GREATER THE MASS of an object, the MORE FORCE it can exert The GREATER THE ACCELERATION, the MORE FORCE it can exert

With this equation we can solve for each variable Chapter 10 Main Ideas Details 2nd Law equation With this equation we can solve for each variable FORCE = MASS X ACCELERATION F M A Mass = Force/Acceleration Acceleration = Force/Mass

Question #1 Chapter 10 2nd Law example Main Ideas Details 2nd Law example Question #1 A speedboat pulls a 55kg water skier at an acceleration of 2.0m/s/s. Calculate the net force that causes this acceleration. Force= Mass x Acceleration 55kg X 2m/s/s _______ 110 N

Question # 2 What is the force that is need to pull a 25kg wagon at an acceleration of 14m/s/s? F=mxa 25kg x 14m/s/s =350N

Question #3 What is the acceleration of a 60kg Boa Constrictor with a force of 120N? a=f/m 120N / 60kg = 2 m/s/s

Next Now go to Newton’s 2nd law to solve some word problems.
