WebAug 23, 2024 · I think that's what another Newton's law is for, the one on actio and reactio. If there is no net acceleration that shows that there is a force that counteracts acceleration. If you skip that hinderance you get acceleration which obeys all laws. – Peter Bernhard. Nov 28, 2024 at 12:07. Add a comment. WebJan 17, 2024 · Modeling this using Newtonian mechanics might be a little difficult as the length of the pendulum and the mass of the bob are changing with time. An alternative would be to look at the Lagrangian approach in which you consider the energies (kinetic and potential): L = T − V = 1 2 m ( t) ( ℓ ˙ 2 + ℓ ( t) 2 θ ˙ 2) + m g ℓ ( t) cos θ.

An intuitive explanation: d m = ρ d V. says that a little bit of mass near a point is (approximately) equal to the density at that point times a little bit of volume. This is correct: it is pretty much just the definition of density. On the other hand, d m = V d ρ. " - Deal with varying mass
