Explain balanced and NFL Learning: unbalanced forces mathematically and graphically Second Law of Motion Video with respect to acceleration to establish the relationship between net force, acceleration, and mass: a F α Physics Classroom and a 1/m (no α trigonometry). Note: is α Motion Simulation symbol for angular acceleration. Third Law of Motion Explain qualitatively and quantitatively the relationship between force, mass and acceleration– the greater the Newton’s Laws Summary force on an object, the greater its change in motion; however, the same amount of force applied to an object with less mass results in a greater acceleration. While the second law describes a single object, forces always come in equal and opposite pairs due to interaction between objects. Give examples of interaction between objects describing Newton’s third law – whenever one object exerts a force on another, an equal and opposite force is exerted by the second on the first. The third law can be written mathematically as FA→B = -F B→A. Students should explain why these forces do not each “cancel other out”.
