VEX V5 Hardware
For 100. What is the official name of the VEX V5 motor?
Smart Motor or Actuator
For 100. What does the "while" loop do?
Repeats nested code as long as the given condition is true.
i.e. While button pressed, move motor forward.
For 100. What is a gear ratio?
The ratio of the number of teeth on two gears.
For 100. What is the difference between a circle's radius and diameter?
Radius is half of the circle's diameter. Diameter is the width of the circle.
For 100. What is the official name of the "button" sensor
Bump Sensor

For 200. What block increases a motor's speed?
set drive velocity to 50%.
Need the keywords set and velocity.
For 200. What is the definition of torque?
A rotational force.
For 200. What are the three dimensions in which we and our robots move?
X, Y, Z
For 200. How many Line Trackers sensors are needed to accurately track a line?
3 Line Trackers
For 300. What type of cord charges BOTH the VEX V5 Brains and VEX Controllers?
Micro USB
For 300. Name three different types of variables.
Characters, Strings, Integers, Doubles, Floats, Booleans, etc.
For 300. What is the name of the gear that receives power from the DRIVER/DRIVING gear?
The Driven Gear.
For 300. If a motor turns a gear with 12 teeth, which turns a gear with 36 teeth, how much slower does the second gear turn?
3 times slower
For 300. How do you connect a sensor to the VEX V5 Brain?
Connect it to one of the 3-wire ports.
For 400. What is the difference between a C-Channel and a U-Channel?
For 400. What are the three possible coding languages for VEX V5?
C++, Python, Blocks/Scratch
For 400. What is the formula for Speed?
Speed = Distance / Time
For 400. A gear system has two sets of gears. The first set has a 2:1 ratio, and the second set has a 4:1 ratio. What is the overall gear ratio?
8:1
For 400. This sensor is typically used to detect the end of travel for a moving part.

Hex Nuts - Flat, Normal
Keps Nuts - Teeth
Nylock Nuts - Plastic/Nylon in the center
For 500. How do you add a sensor to your VEX V5 code?
Add a device, 3-wire, sensor.
For 500. What equals speed * torque?
speed * torque = power
For 500. How do you convert radians to degrees?
Degrees = Radians * (180 / pi)
For 500. How does the Ultrasonic Sensor measure distance?
By measuring the time it takes sound waves to return.
