Learn how to use force diagrams to analyze the forces and torques acting on a rigid system. Explore how force and torque can lead to rolling in different situations.

Apply your knowledge of torque in this set of free practice questions.

A torque is the rotational equivalent of a force. When a torque is applied to an object it causes the object to rotate. Learn how forces create torques and how to calculate the net torque on a rotating object.

Moments and torque are related but not the same thing. For a rotating object, the moment is established from the axis of rotation, ie. the imaginary line about which the object is rotating. The moment of …

Rotational inertia is a property of any object which can be rotated. It is a scalar value which tells us how difficult it is to change the rotational velocity of the object around a given rotational axis.

Introduction to torque and equilibrium concepts in physics explained with interactive videos on Khan Academy.

An introduction to torque, a force that causes rotation. Understand how torque is calculated as the product of force and distance, and how it differs from work. Learn about the direction of torque and …

David explains moment of inertia and the rotational version of Newton's second law and shows how to solve an example problem.

David explains how to determine the torque exerted by a non-perpendicular force.
