# Torque FAQs:

Q: Is torque a pseudovector?

A: Yes, for point particles, it is given by the cross product of the position vector and the force vector.

Q: Is torque in pounds-force feet and rotational speed in revolutions per minute?

A: Yes, and the above equation gives power in foot pounds-force per minute.

Q: Is torque sometimes listed with units that do not make dimensional sense?

A: Yes, such as the gram-centimeter.

Q: Is torque allowed to act through a rotational distance?

A: Yes, and it is doing work.

Q: Is torque part of the basic specification of an engine: the power output of an engine is expressed as its torque multiplied by its rotational speed of the axis?

A: Yes.

Q: Is torque in newton metres and rotational speed in revolutions per second?

A: Yes, and the above equation gives power in newton metres per second or watts.

Q: Is torque referred to as moment of force?

A: Yes, and usually shortened to moment.

Q: Is torque referred to using different vocabulary depending on geographical location and field of study?

A: Yes.

Q: Was torque apparently introduced into English scientific literature by James Thomson?

A: Yes, and the brother of Lord Kelvin, in 1884.

A: Yes.

Q: Is torque increased?

A: Yes, and product of which does not change.

Q: Is torque entirely different concepts?

A: Yes, so the practice of using different unit names helps avoid mistakes and misunderstandings.

Q: Is torque defined mathematically as the rate of change of angular momentum of an object?

A: Yes.
