How do gears affect the torque and speed of a mechanical system?

• Gears cannot change torque or speed.

• Gears can only increase speed, not torque.

• Gears can increase or decrease speed and torque, depending on their size and arrangement.

• Gears reduce both speed and torque to make systems safer.

What is a unique advantage of using VEX Robotics parts for educational purposes?

• They are only compatible with advanced robotics systems.

• They encourage learning through hands-on building and problem-solving.

• They are less durable, requiring frequent replacement and learning opportunities.

• They require no instructions, promoting intuitive learning only.

What is the primary function of a worm gear in a mechanical system?

• To increase the speed of operations

• To decrease the speed and increase torque

• To transmit electrical power

• To cool down the system
