Engineering Design Process
Requirements of a design to be successful.
Criteria
Distance/Time such as km/hr
Speed
Every action has an equal opposite reaction.
Newton's 3rd Law
A push or pull
Force
Energy of motion
Kinetic Energy
Limitations or restrictions of a design.
Constraints
Speed and direction of an object
Velocity
The acceleration of an object depends on the mass and force applied. (F = ma)
Newton’s 2nd Law
The energy in joules used as a force moves an object over a distance.
Work
A process that absorbs heat (gets colder)
Identifying a problem is the ____ step in the EDP.
1st Step
The change in velocity during a period of time
Acceleration
An object at rest remains at rest, and an object in motion remains in motion unless acted on by an unbalanced force.
Newton’s 1st Law
The equation for work
(Work = Force × Distance)
Stored energy because of an object’s position
Potential Energy
Trying something over and over again.
Iteration
It takes Jay 3 hours to travel 75 kilometers. What is Jay's Speed?
25 km/hr
Newton's 2nd Law
Tyrone is sweating trying to push a large rock but it is not moving. Is Tyrone doing work?
No
A process that releases heat (feels hotter)
Exothermic
A man is driving on the H-1 towards Ewa Beach at 60 km/hr. What is his velocity?
50 km/hr, west
A sleeping dog does not move unless you poke it.
Newton's 1st Law
100 Joules
When a roller coaster is free falling down a drop.
