100

The code run continuously, where sensor reading + decision-making + motor control happens, over and over

What is loop()?

100
The friction formula

What is FF= μN?

100

The power source of a car

What is the engine?

100

A push or pull that acts on an object as a result of that object's interaction with its surroundings

What is a force?

100

A student is connecting their wires between the breadboard and Arduino, while it is plugged into the laptop. Facilitators should..

What is reviewing safety basics with the students and monitoring closely during this activity?

200

A closed loop path allowing electricity to flow from a power source, through conductors and components, back to the source

What is a basic circuit?

200

The difference between the normal and subscript F's in the formula

What is a Force and type of force?

200

The smoothest path through a turn, usually entering wide

What is the racing line?

200

Requires two objects to be touching; ex. the tire pushing on the track

What are contact forces?

200

Waymo uses laser-based sensing to map its surroundings

What is LIDAR (Light Detection and Ranging)?

300

You are entering the freeway, approaching 60 MPH, you must shift into the ___ gear

What is the 4th gear?

300

In the formula, higher μ or higher N represents

What is more grip or more weight pressing down, causing more friction force?

300

Where a driver starts slowing down before a turn

What is the braking point?

300

You are driving on the freeway and all of a sudden you hit the brakes, causing the car to decelerate.

What is a net force backward?

300

You are at a full stop and traffic isn't moving, you are in ___ gear

What is Neutral?

400

If your wheels were locked together and had to spin at the exact same speed, your car would fight itself every time it turned

What is missing a differential?

400

You are drifting through a turn; connect your observations to the formula FF= μN

What is lower μ caused by the surface, producing greater FF, resulting in loss of static traction and drift?

400

The fastest section of a track where there is full acceleration

What are the straights in a track?

400

You are driving the car and as you hit the gas, the car accelerates

What is an unbalanced net force?

400

You are oversteering at a turn, causing the back of the car to swing out more than intended, you must..

What is steering into the skid and gradually easing off the gas (power)?

500

The conversion of engine power into usable speed/torque through a set of gears

What is a transmission?

500

You rapidly accelerate from a stop, connect your observations to the formula FF=μN 

What is a higher μ, giving the tires more traction and allowing the car to accelerate more efficiently?

500

The tightest point of a turn during a race

What is the apex in a track?
500

You are approaching a green arrow at a stoplight, you decelerate and begin steering right.

What is a sideways net force?

500

You are understeering at a turn, causing the car to continue straight or drift wide, you must..

What is easing off the throttle (power) gently and reducing steering angle?
