Speed remains the same
Speed doubles
Torque is best described as:
The rate at which something moves
A twisting force that causes rotation
The ratio of the force produced by a machine
The speed at which gears turn
Which of the following scenarios involves high torque and low speed?

It decreases the efficiency of tasks
In a gear system, if Gear A has 10 teeth and Gear B has 20 teeth, what is the gear ratio?
1:1
1:2
2:1
1:10
If Gear A (input) rotates faster than Gear B (output), what can be said about the torque of Gear B?
Torque is lower on Gear B
Torque is higher on Gear B
Torque is the same on both gears
Torque is irrelevant in this situation
When would you want to use a low gear ratio in a car?
When driving on a flat highway
When accelerating quickly

Varies torque randomly
Which component is directly responsible for increasing the force in a mechanical advantage?
Speed
Torque
Gear Ratio
Weight
If you need more power to lift a heavy object, which gear ratio would you use?
Higher gear ratio
Lower gear ratio
Equal gear ratio
Any gear ratio will work
In which situation would you prioritize speed over torque?
Lifting heavy weights
Driving on a steep hill
Racing on a flat track
Drilling through hard materials
What does a gear ratio of 1:2 indicate?
The input gear is twice the size of the output gear
The output gear rotates twice as fast as the input gear
The input gear rotates half as fast as the output gear
The output gear has half the torque of the input gear
