Balloon Racer Standards Review

Which law does this picture represent?

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

Testing your prototype and redesign is a very important part of the engineering design process.  Why?

• Redesigning and testing is so much fun!
• It fixes design issues, makes it better, and allows your solution to be as successful as possible.
• It allows you to make as many prototypes as you can.
• It allows you to ask questions and define problems.

Which balloon racer car will require more force to accelerate?

• The car with the most mass on the right.
• The car with the least mass on the left.

Factors that limit or restrict a design, such as having limited amount of money or time is called

• trade-offs
• constraints
• patent
• engineers

Which of the following was a constraint in the balloon powered car project?

• size
• time
• material
• internet resources

What is the main transfer of energy taking place in the balloon racer car?

• thermal to sound
• potential to kinetic
• kinetic to potential
• sound to thermal

If 3 cars had the same body mass, which car will accelerate the greatest?

• A car with a balloon with little air.
• A car with a balloon with medium air.
• A car with a balloon with a lot of air.

Why doesn't the balloon racer car travel forever?

• The force of friction causes the balloon car to slow down.
• An outside force, like a wall or other object may make it stop.
• Both answers are correct

You noticed your car did not travel as far as your neighbor's car.  Which is one reason why?

• Your car had more mass and less force.
• Your car had more kinetic energy.
• Your car had less mass and more force.
• Your car had more potential energy.

What is the first step in the engineering design process?

• research the problem
• identify the need or problem
• construct a prototype
• redesign
