Answer the following question given this paragraph:   In a wheel and axle, force may be applied either to the wheel or to the axle. This force is called the input force. A wheel and axle does not change the direction of the input force. However, the force put out by the machine, called the output force, is either greater than the input force or else applied over a greater distance.   Q: What is the term for the force applied to a wheel and axle?   A:
OPTIONS:
- velocity force
- momentum
- output force
- input force
input force
