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.
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 body …
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.
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 …
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.
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 …
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 …
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 rolling in …
Moment siły (artykuł) | Khan Academy
Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire …
