Torque

Torque. Torque ≡ the action of a leveraged force . Torque is the ability of a force to cause rotation or a turning motion. Unbalanced torque provides a rotational acceleration. Torque τ has two components: a perpendicularly applied force, F, and a leverage arm distance, r

Torque

Torque. T orque is an influence which tends to change the rotational motion of an object. One way to quantify a torque is Torque = Force applied x lever arm=F x r The lever arm is defined as the perpendicular distance from the axis of rotation to the line of action of the force. . Torque.

Torque

Torque. We know that Newton’s second law ( ) explains that the net force is the source of an object’s acceleration. What is the source of a rotating object’s angular acceleration? It can’t be just a force, because it matters where on the object that force is applied.

Torque

Torque. AP Physics 1. Causing Rotational Motion. In order to make an object start rotating about an axis, a torque is required. Torque includes not only the amount of force applied but also the distance from the axis to which the force is applied. Distance from axis is called the lever arm.
