What is the definition of Kinetic Energy?
The energy an object has because of its motion
What causes an object to move - a balanced force or an unbalanced force?
Unbalanced force
In your own words, what is a prototype?
A "Practice product"
What is the equation for momentum?

What does KE stand for in the following equation?
KE = 1/2 X m X v2
Kinetic Energy
When 2 or more objects collide, do they each feel the same force or different forces?
Same force
In your own words, what is a tradeoff?
Sacrificing something desirable for something more desirable.
Which cart has the highest momentum?

Neither
What does m stand for in the following equation?
KE = 1/2 X m X v2
Mass
What is the equation for calculating force?
Force = mass X acceleration
In your own words, what is the definition of "criteria"?

A tricycle crashes into a Ford F-150. Which one feels the greater force?
Neither - they both feel the same force
In your own words, what is a "constraint"?
Any sort of limitation on a design.
What is the definition of momentum?
Mass in motion
Name an example of something with kinetic energy
moving car....moving ball... moving anything
What unit is force measured in?
Newtons
Why is it useful to have several different designs for the same product before mass production?
To test them and see which is better.
