Newtonian mechanics discusses the movement of classical bodies under the influence of forces by applying Newton’s three laws. For more general concepts, use [classical-mechanics]. For Newton’s description of gravity, use [newtonian-gravity].

How do I find the acceleration of a particle in this particular condition?
At any point of time, 1 observes that 3 moves towards it with a speed $v+v\cos60^{\circ}=\frac{3}{2}\cdot v$. so the length of side of the equilateral triangle formed by the three particles as a funct …

The chronology of taking approximation changes the answer?
I've found out where the error was, it was not due to chronology of taking approximations, instead I had done error while approximating $\arctan(\sqrt{\frac{h_0}{R}})$. Let $x=\frac{h_0}{R}<<1$, then …

The chronology of taking approximation changes the answer?
The problem is to find the time it takes a particle dropped from a height $h_0$ above the surface of the earth to reach the surface (exactly, not approximately i.e. $g$-value is not constant, in the l …

which force should come out to be the same in both frames
Suppose that a long cart is moving at a constant relativistic speed with respect to the ground. Sand is falling on it from negligible height(from the same place and zero horizontal velocity with respe …

What's the amplitude of the energy loosing oscillator as a function of time?
The problem comes from 'introduction to classical mechanics' by David Morin. It is as follows:
A chain with mass density $\sigma$ kg/m hangs from a spring with spring
constant $k$. In the equilibrium …
