VEX IQ - Tug of War

Which of the following best describes 'force?'

• A push or pull that can change an object's motion.

• Another name for the wheels in the VEX IQ Kit.

• A visible indicator on a robot brain that shows which direction the robot is moving.

• What we use to name our robot in VEXcode IQ.

What happens when forces are balanced on your robot?

• The robot moves

• The robot will not move

• The robot's mass will decrease

• The robot's mass will increase

Which of the following best describes an unbalanced force?

• All the forces are balanced

• Force applied in one direction is the same as the force applied in the opposite direction

• Force applied in multiple directions balance each other out

• Force applied in one direction is greater than the force applied in the opposite direction

Initial force input for your robot comes from the

• Wheels

• Shafts

• Motors

• Gears

In order for a robot to push or pull another object, the force generated by the robot must be

• Greater than any opposing forces.

• Less than any opposing forces.

• Equal to any opposing forces.

What is a gear train?

• A type of VEX IQ robot

• A mechanism made up of two or more gears

• One gear that is moved to different places on a robot between builds

• A type of force

Which of these configurations in a gear train would cause increased speed?

• Two gears of the same size

• A small gear driving a big gear

• A big gear driving a small gear

Which of these configurations in a gear train would cause increased torque?

• Two gears of the same size

• A small gear driving a big gear

• A big gear driving a small gear

Using gears for mechanical advantage allows us to multiply or reduce that amount of _____ force without having to adjust the _____ force or change the direction of rotation.

• Directional, speed

• Speed, torque

• Mechanical, electrical

• Output, input

TRUE or FALSE: Center of mass is the point on an object where force is applied so that it moves without rotation.

• TRUE

• FALSE
