Can someone explain torque, as in not the mathematical, but how it relates to rotational motion? How does it relate to force?
Torque (more precisely: moment) is to rotational motion what force is to linear motion. Applied force changes the linear momentum of a system. Applied torque changes the angular momentum of a system. When you turn a door knob, unscrew a jar's lid, open a garden gate, it is the torque that you apply that acts on the body and produces its motion.
a torque changes the speed of rotation. (angular velocity) it can start a rotation of stop it you can think about two kids on a see saw It's not just the weight of the kids (force) the determes which way it will go, it's also their positons If you sit closer to the axis you are going to lose... thats a smaller torque T=F*R
