![]() In addition, a summative assessment unit quiz is provided as an attachment to lesson 3, to be administered after completion of all three lessons and the activity. The individual lessons include assessment suggestions to implement throughout the unit (discussion questions, exit ticket, homework, etc.). Newton's third law of motion: For every action, there is an equal and opposite reaction. Newton's second law of motion: Force = mass x acceleration (aka F= ma) ![]() Newton's first law of motion: Unless an unbalanced force acts on an object, an object at rest stays at rest and an object in motion stays in motion. ![]() Learning how Newton's laws apply in everyday situations and devices enables students to be able to describe how objects move and prepares them for the study of more complex physics concepts. To design objects that perform as we want and are safe, engineers must fully understand the workings of the natural physical laws. This includes structures, vehicles and objects such as bridges, rockets, aircraft, seat belts, door knobs and medicine delivery systems. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Įngineers apply basic physics concepts such as Newton's laws of motion in a wide range of situations such as designing all sorts of stationary and moving objects, from the massive to the delicate. In a culminating activity, students apply their knowledge of forces, friction, acceleration and gravity in an experiment to measure the average acceleration of a textbook pulled along a table by varying weights, and then test the effects of friction on different surfaces. Lesson 3 builds on the previous two lessons with a review and then introduces Newton's third law of motion. Lesson 2 builds on lesson 1 with a review and then introduces Newton's second law of motion. ![]() Lesson 1 starts with inertia, forces and Newton's first law of motion. For each lesson, a combination of class demonstrations and PowerPoint® presentations are used to explain, show and relate the concepts to engineering. This law lies behind the design of rocket propulsion, in which matter forced out of a burner at high speeds creates an equal force driving the rocket forward.Through a series of three lessons and one activity, students are introduced to inertia, forces and Newton's three laws of motion. Thus, if one body exerts a force F on a second body, the first body also undergoes a force of the same strength but in the opposite direction. ♦ Newton's third law states that for every action there is an equal and opposite reaction. Expressed mathematically, F = ma, where F is the force in Newtons, m is the mass of the body in kilograms, and a is the acceleration in meters per second per second. ♦ Newton's second law states that a force acting on a body is equal to the acceleration of that body times its mass. This law is also called the law of inertia. ♦ Newton's first law states that a body at rest will remain at rest, and a body in motion will remain in motion with a constant velocity, unless acted upon by a force. These laws form the basis of classical mechanics and were elemental in solidifying the concepts of force, mass, and inertia. The three laws proposed by Sir Isaac Newton concerning relations between force, motion, acceleration, mass, and inertia.
