Finding motorcycle turning radius based on lean angle
The explanation by @user121330 uses arguments in the non-inertial frame of the rider. That'll work but I feel it is an overly complicated way to do it. Here is how you work it out in a simpler, ...

Finding motorcycle turning radius based on lean angle
Fundamentally, the shape of the tire will impact the way that a bike turns and how much turning results from leaning and how much comes from turning the front wheel. Fortunately, you can ignore all ...

Velocity and Angular Velocity Equations for Cue-Ball Interactions
How did the authors derive this equation for force?
with those equations you can obtain the "force" F
\begin{align*}
&M\,(\vec{v}_c-\vec v_0)=-F\,\hat e_F\\
&m\,\vec{v}_s=F\,\hat ...

Rotating a lever — small end has more force but less speed?
There are two errors here.
First, $ F_{2} = F_{1}\frac{R}{r} $ is about the balancing of two torques in static equilibrium. That is, the usually case where this holds is where $F_1 R$ is one torque, ...

Rotating a lever — small end has more force but less speed?
What accelerates object A is not the force $F_1$ that you applied to it, it's the net force that it experiences.
$F_1$ is one component of the net force, but there is also a reaction force from the ...

Angular Acceleration of Spinning Body About a Rotating Axis
Let's first start with a picture. The object (blue ball) is rotating around the AB axis with angular velocity $\vec\omega_0$.
Next, the $AB$ axis is rotating around the vertical with an angular ...
