  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. Learn about the direction of torque and …

  3. 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 …

  4. Rotational inertia (video) | Khan Academy

    If you apply a force further away from the axis of rotation, the torque will increase. Even though both depend on radius, the torque and moment are completely independent (ex. you can apply the force …

  5. Rotational inertia (article) | Khan Academy

    Learn how the distribution of mass can affect the difficulty of causing angular acceleration.

  6. Intro to torque (video) | Khan Academy

    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.

  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. Review of rotation (video) | Khan Academy

    The torque and the clockwise direction would be one meter times three newtons to find the torque from the three newton force. Plus you wouldn't use two meters for the r of the one newton force.

  9. Rotational version of Newton's second law - Khan Academy

    Remember torque is R times F times sine theta, but let's make it simple. Let's say the angle's 90 so that sine theta will end up being one 'cause sine of 90 is one.

  10. Constant angular momentum when no net torque - Khan Academy

    We have the same analogy here. The analog for force in the rotational world is torque, it's obviously this force times the kind of radial, times that radial distance. But if you take torque times how long you're …
