• trebuchet

• projectile

Air resistance pushes against falling

objects and __________________.

• Speeds them up

• Keeps them afloat

A prototype is a

• miniature plastic model

• fake model of the real thing.

• clay model that looks like a car.

• model that engineers build to test and improve their design.

When engineers go through an iterative testing process they

• improve the prototype by trying stuff randomly.

• test, evaluate, and improve the prototype over and over again.

• test the car by crashing it once and then getting it towed.

• Design what the prototype will look like before they build it.

What does it mean to optimize a design solution?

• To make it worse

• To make it better

• To make it as good or effective as possible

• To hope it does not break
