Finding torque for angled forces - Khan Academy
The angle between the F vector and the R vector is the angle we're looking for when we're solving for the torque exerted by a certain force. So let's use this formula.
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
Examine how torque in rotational motion is analogous to force in linear motion. Learn how torque relates to force, position, and angle, and how force diagrams can be used to analyze forces and torques …
Torque and equilibrium review (article) | Khan Academy
To produce a torque, the force F must be applied at some distance r away from the pivot point. Since only the perpendicular component F ⊥ produces torque, the equation includes sin θ (see Figure 2 …
Torque acting on current loops (video) | Khan Academy
A current-carrying coil kept in a magnetic field experiences a torque, which is the cross product of the magnetic moment and the field vector. Hence, the torque is maximum when the dipole moment is …

Rotational version of Newton's second law - Khan Academy
You add up all of the torques where torque's trying to rotate it one way would be positive, and torque trying to rotate it the other direction would be negative, so you'd have to make sure signs are correct …
Rotational kinematics (article) | Khan Academy
The angle through which a point on a rigid system rotates during a given time interval is called the angular displacement (Δ θ). We must specify a direction for angular displacement.
Angular velocity (article) | Khan Academy
Now, we could head pretty far down this road, trying to model the physics of angular acceleration using the concepts of torque and moment of inertia. That level of simulation is beyond the scope of this …
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.
