Newton’s Second Law of Motion Chapter 4, Section 3 Pg

Newton’s Second Law of Motion The net force acting on an object causes that object to accelerate in the direction of the net force. The net force acting on an object causes that object to accelerate in the direction of the net force. Greater the force = Greater acceleration. Greater the force = Greater acceleration. F F

Inverse relationship between mass and acceleration!!! Inverse relationship between mass and acceleration!!! The greater the mass, the more force it takes to accelerate an object at the same rate of a less massive object!!! The greater the mass, the more force it takes to accelerate an object at the same rate of a less massive object!!! Newton’s Second Law of Motion F F

The relationship between force, mass, and acceleration is expressed as: The relationship between force, mass, and acceleration is expressed as: ΣF = ma SI unit = kg x m/s² = N Newton’s Second Law of Motion

What is the force of a baseball weighing 0.06 kg that is accelerating towards a wall at 5,500 m/s²? What is the force of a baseball weighing 0.06 kg that is accelerating towards a wall at 5,500 m/s²? Sample Problem m = 0.06 kg a =5,500 m/s² F = ma= (0.06 kg x 5,500 m/s²) =330 N
