Work using angle vs. displacement [closed]
I am trying to calculate the work done on this wheel as it undergoes one full revolution, and is rolling without slipping.
I am aware that work can be calculated either using the integral of force ...

Do rigid bodies experience work greater than or equal to that of point particles?
Consider the following two scenarios in outer space:
A yo-yo whose string is pulled by a constant force.
The same yo-yo as before although this time, the string is fully unwound and attached to the ...

Work Done on a rotating thin rod by hinge Forces
So I was studying the concept of rotational energy through a video, and the guy presented a problem,
It's like this:
"Suppose a thin rod of mass M and length L/2 is hinged from one end. Then, it ...

Conceptual question about rotational and translational kinectic energy
My real life problem is to calculate initial translational and angular velocities of a vehicle in a loss of control to a stop (the vehicle will translate and rotate about it's center of mass.)
Initial ...

Does a force does more work on an extended body?
$$ \underline{\pmb {Assumption}}$$
Assume a place free from any gravitational or other kind of influences (like friction, drag, etc.). Now assume a thin cylindrical rod of mass $M$ and length $l$. ...

Is angular work equivalent to linear work?
When considering the definition of angular work, I assumed that it should reduce to the definition of linear work in order to tie in quite nicely with conservation of energy. However, further ...
