In the study of dynamics, engineers apply Newton's second law to predict the motion of an object experiencing a net force. Newton's second law of motion provides the foundation for much of the mathematics in engineering mechanics. This engineering curriculum aligns to Next Generation Science Standards ( NGSS). This lesson is the second in a series of three lessons that are intended to be taught as a unit. They also learn that Newton's second law is commonly used by engineers as they design machines, structures and products, everything from towers and bridges to bicycles, cribs and pinball machines. Students come to understand that an object's acceleration depends on its mass and the strength of the unbalanced force acting upon it. Both the mathematical equation and physical examples are discussed, including Atwood's Machine to illustrate the principle. After a review of force, types of forces and Newton's first law, Newton's second law of motion is presented. Students are introduced to Newton's second law of motion: force = mass x acceleration.
