  1. Force diagrams and rolling (article) | Khan Academy

    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.

  2. Introduction to torque (video) | 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.

  3. Angular momentum (video) | Khan Academy

    Just as kind of torque is the thing that can change how something rotates, and force is the way that something changes how something translates it, and torque is force times distance from the center of …

  4. Cross product and torque (video) | Khan Academy

    Torque is defined as the cross product of the moment arm with the force so T = r x F is thee correct way to write it. The torque vector is at right angles to the force and moment arm.

  5. Intro to torque on a dipole in uniform electric field

    When an electric dipole is placed in a uniform field, it experiences a torque. This torque tries to align the dipole in the direction of the field. Let's explore more.

  6. Torque and equilibrium review (article) | Khan Academy

    Work is a scalar that describes how much energy was transferred to a system and its units are equivalent to Joules. Torque describes a vector of how much twisting action a force puts on a body …

  7. Physics archive | Science | Khan Academy

    The physics archive contains legacy physics content, and is not being updated with new content. For our most up-to-date, mastery-enabled courses, check out Middle School Physics, High School Physics, …

  8. Torca (artículo) | Torca y momento angular | Khan Academy

    La terminología empleada al describir la torca puede ser confusa. Los ingenieros utilizan a veces el término fuerza de torsión, o momento de fuerza indistintamente al de torca. También se le llama el …

  9. Torque (artigo) | Torque e momento angular | Khan Academy

    Torque é uma medida de força que pode causar um objeto a girar ao redor de um eixo. Assim como a força é o que faz um objeto acelerar em cinemática linear, torque é o que faz com que um objeto …

  10. Rotational inertia (article) | Khan Academy

    F T = m a T . this can also be written as F T = m (r α) . Newton's 2ⁿᵈ law relates force to acceleration. In rotational mechanics torque τ takes the place of force. Multiplying both sides by the radius gives the …
