Sense: noun/1
Torque, force, power, and moment are often confused because all relate to motion and energy. Force is the broadest term — any push or pull that changes an object's movement — while torque specifically describes a force that causes rotation around a centre. Power differs by adding the dimension of time: it is the rate at which work is done. A car engine may produce high torque (strong twisting force) but low power if it cannot sustain that force at high speed. Moment is the formal physics term for torque (force × distance from pivot) and is preferred in scientific writing; torque is more common in automotive and engineering contexts. For example, 'Applying a force of 10 N to a spanner creates a torque of 5 Nm at the bolt.'

Etymology
The word torque comes from Latin 'torquere', meaning 'to twist'. It entered English in the late 1800s as a physics term for rotational force. The verb form developed later as engineers needed a shorter way to say 'apply a measured twisting force to a fastener'.
