1 Engineers create, develop and manufacture machines, structures, processes and systems that impact society and may make humans more productive.
184.108.40.206.1 Identify a common engineered system and evaluate its impact on the daily life of humans.
220.127.116.11.2 Recognize that there is no perfect design and that new technologies have consequences that may increase some risks and decrease others.
18.104.22.168.3 Describe the trade-offs in using manufactured products in terms of features, performance, durability and cost.
22.214.171.124.4 Explain the importance of learning from past failures, in order to inform future designs of similar products or systems.
2 Engineering design is the process of devising products, processes and systems that address a need, capitalize on an opportunity, or solve a specific problem.
126.96.36.199.1 Apply and document an engineering design process that includes identifying criteria and constraints, making representations, testing and evaluation, and refining the design as needed to construct a product or system that solves a problem.
188.8.131.52.2 For an object traveling in a straight line, graph the object's position as a function of time, and its speed as a function of time. Explain how these graphs describe the object's motion.
2 Forces have magnitude and direction and affect the motion of objects.
184.108.40.206.1 Recognize that when the forces acting on an object are balanced, the object remains at rest or continues to move at a constant speed in a straight line, and that unbalanced forces cause a change in the speed or direction of the motion of an object.
