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 ...

Is the value of the work done by the forces acting on a rigid body frame dependent?
I was going through the definition of "Work of Forces Acting on a Rigid Body" in Wikipedia .
Here they have mentioned that work done can be calculated by taking any reference point on the ...

Work and mechanical energy relationship for a rigid body
For a single particle in a conservative field, I know that the work done by an external non conservative force $W_n=\Delta M$ where $\Delta M$ is the total mechanical energy.
Is the same true for an ...

A Question about Virtual Work related to Newton's Third Law
In describing d'Alembert's principle, the lecture note I was provided with states that the total force $\mathbb F_l$ acting on a particle can be taken as,
$$\mathbb F_l=F_l+\sum_mf_{ml}+C_l,$$
where $...
