    That last one has me stumped… Their hands look like they’re good at sprinting from a standstill? 🤔

      I’m pretty sure they only talked about torque and nothing about sprinting.

      In case you learned about torque from a gearhead, torque is essentially a measure for the rotational effect of force around a fulcrum. So, since most (all ?) of our limb motions are turning around some pivot point (joints), we can measure torque for all of those.


      Now I realise how hard it was for them to define torque to me as a child.

        Yeah, English isn’t my first language and the first time I heard the word was watching Top Gear as an adult a decade or two ago, so that’s my most immediate association 😄

      What does toque have to do with sprinting from a standstill? Torque of more like, capacity to put out mechanical energy. I read this as “your arms look capable of lifting heavy weights”.

          Yeah. Torque (at the wheel) multiplied by the wheel radius will give the force that the car exerts on the ground, parallel to the ground. That will finally determine the acceleration of the car.

          Though from what I remember, torque - as given with a car’s information - is measured at the flywheel, so there’s more calculations you will have to do to get the correct answer.
