Euler’s equations of motion for a rigid body can be interpreted as a rewriting of Newton’s second law for rotations in a rotating frame. They basically tell us the sum of the torques equals the rate of change of the body’s angular momentum, In the rotating frame. Do we then not need to take into account inertial forces when computing the torques in rotating coordinates?

A ball of mass 5kg is attached to a string of length 120 cm and rotating vertically at a speed of 10 cm/s. what is the tension of the string when the ball is farthest to the right from the center? (neglect both the string's mass and air resistance)

I have been given the potential of a simple harmonic oscillator:
$V = \frac{1}{2} k x^{2}$
I want to calculate the value $x (t)$ of a particle moving in this potential, with initial conditions $x (t = 0) = 0$ and $v (t = 0) = v_{0}$ . How would I go about doing this in simple classical mechanics?

Why is Newton's second law only second-order in position? For instance, could there exist higher-order masses $m_{i}$ with
$F (x) = m \ddot{x} + \sum_{i = 3}^{\infty} m_{i} x^{(i)} ?$

I want to prove that the acceleration in a orbit at a given point r=(x,y) is $a = - \frac{G M}{R^{3}} r$ . I know that N2 gives $F = m a$ substituted into $F = \frac{G M m}{R^{2}} r$ gives $a = \frac{G M}{R^{2}} r$ . How can you prove $a = - \frac{G M}{R^{3}} r$ ?

Is there a more fundamental reason for the Classical Lagrangian to be T−V and Electromagnetic Lagrangian to be T−V+qA.v or is it simply because we can derive Newton's Second Law and Lorentz Force Law with these Lagrangians respectively?

Before you start solving Newton's second law practice problems or explore various equations for your lab report or specific course, it's essential to learn the theory. In basic terms, it says that the speed an object gain is taking place when a certain force has an effect on a mass, which is also represented by an object. For example, when we ride a bike, we can see how the force is applied. The bike represents the mass. The force that we apply is what provides an effect. You can take a look at similar questions as you explore Newton's second law examples based on laboratory tests and experiments. The other example of Newton's Second Law is the difference between pushing an empty mall cart compared to the one that's filled.
