300
A person who uses both science and technology to solve problems.
What is an engineer?
400
An aerodynamic force that opposes an aircraft's motion through the air.
What is drag?
400
Law that states an object at rest remains at rest and an object in motion remains in motion unless acted upon by an unbalanced force.
What is Newton's first law of motion?
400
A sequence of actions that the system undergoes toward its goal.
What is the process?
400
Any factor that limits a design.
What is a constraint?
400
Potential energy related to an object's height.
What is gravitational potential energy?
500
In order for a rocket to fly, this force must be greater than the mass of the rocket.
What is thrust?
500
Law that states force equals mass times acceleration (f=ma)
What is Newton's 2nd law of motion?
500
Five parts of a technological system.
What is goal, input, process, output, and feedback?
500
8 steps of the engineering design process.
What is (1)identify a need or problem, (2) research the problem, (3) develop possible solutions, (4) select the best possible solution, (5) construct a prototype, (6) Test and evaluate, (7) communicate the solution, (8) redesign.
500
Two basic types of energy.
