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.
Unit 5: Torque and rotational dynamics - Khan Academy
Learn how torque relates to force, position, and angle, and how force diagrams can be used to analyze forces and torques acting on a rigid system. Explore how force and torque can lead to …
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.
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 …
Finding torque for angled forces (video) | Khan Academy
Torque is a force that causes something to start rotating, or to change its rotation. So the only component of this force, of this 10 newtons that is gonna cause this door to rotate, is this …
Cross product and torque (video) | Khan Academy
And that is because torque is defined as the cross product between the radial distance from your axis of rotation and the rotational force being applied. So these are both vectors.

ଜଳବାୟୁକୁ ବୁଝିବା (video) | ପାଣିପାଗ ଏବଂ ଜଳବାୟୁ
What’s the difference between weather and climate? In this video, we explore how long-term weather records help define a region’s climate and why that matters! Learn about the five …
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 …
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.
