Torque is a measure of the force that causes an object to rotate around an axis. It is represented by the symbol 'τ' and is measured in units of newton-meters (Nm).
The formula for torque is τ = r x F, where 'r' is the distance from the axis of rotation to the point where the force is applied and 'F' is the magnitude of the force.
Torque is directly proportional to the force applied and the distance from the axis of rotation. This means that a larger force or a larger distance from the axis of rotation will result in a larger torque.
The force that creates torque is called the 'torque force' or 'rotating force'. It is the force that is applied at a distance from the axis of rotation and causes an object to rotate.
Torque affects rotational motion by causing an object to rotate around an axis. The greater the torque, the faster the object will rotate. Additionally, torque can also change the direction of rotational motion.
